Sulfuric acid (H2SO4) is the catalyst for the reaction. Sulfuric acid will dissociate in solution to give H+ and HSO4-. The H+ will start the reaction. The 1-hexene\'s double bond will attack the H+ (proton) and then a carbocation will form. The MOST stable carbocation will form and here you have a choice between a primary and secondary carbocations. The more substituted a carbocation is then the more stable it will be and therefore the secondary carbocation forms. H2O (water) which is the solvent and the nucleophile will attack the carbocation. The intermediate species will have a formal charge of +1 and will lose a H+ (proton) to give a neutral species. The reaction is called acid catalyzed hydration of alkenes. H2SO4 is not too friendly and needs to be used in catalytic amounts probably a few drops. The reaction will be an instant reaction Solution Sulfuric acid (H2SO4) is the catalyst for the reaction.

Topic 08 introduction
This document provides an introduction to acids and bases, including:
1) How acids and bases are defined according to the Arrhenius, Bronsted-Lowry, and Lewis theories. Acids donate protons while bases accept protons.
2) Examples of strong acids like HCl and weak acids like acetic acid. Strong acids fully dissociate in water while weak acids only partially dissociate.
3) The pH scale measures hydrogen ion concentration from 0-14, with lower values being more acidic and higher more basic. Neutral solutions have a pH of 7.
Acids and bases p pt
This document defines acids and bases according to the Arrhenius model and discusses their properties in aqueous solutions. It also explains acid-base titrations for determining concentrations and defines pH. Buffers are formed from a weak acid and its conjugate base or weak base and conjugate acid and do not experience large pH changes upon addition of acids or bases.

What we\'re looking for here are salts in which the anion will not accept protons to form a
stable molecular species. That is, a compound will dissolve in dilute HCl if the reaction: X- +
H+ ------> HX occurs to some extent. But this is just an acid association reaction (the reverse of
the more common acid dissociation reaction). Thus, what we want are acids that do not fully
ionize, or in other words, salts of weak acids. The strong acids are: HNO3, HClO4, HI, HBr,
HCl, and H2SO4. So, salts of NO3-, ClO4-, I-, Br-, Cl-, and HSO4- will not dissolve with dilute
HCl, others will (at least to some degree). Looking at the salkts you have listed, that means that:
AgNO2, Hg2SO4, AlPO4, NiCO3, Cu2S, and CaF2 will dissolve (whole or in part) in dilute
HCl.

Theories
The document discusses several theories of acids and bases:
1. According to Arrhenius, acids are compounds that produce H+ ions in water and bases produce OH- ions. Strong acids fully dissociate while weak acids only partially dissociate.
2. Bronsted and Lowry defined acids as proton donors and bases as proton acceptors. An acid and base always work together in a proton transfer reaction. Some substances can act as both an acid and a base depending on the reaction.
3. Lewis defined acids as electron pair acceptors and bases as electron pair donors.

This document discusses different concepts of acids and bases, including:
1) The Arrhenius concept defines an acid as a substance that produces hydrogen ions (H+) in aqueous solution, and a base as a substance that produces hydroxide ions (OH-).
2) The Brønsted-Lowry concept defines acids as proton donors and bases as proton acceptors. This allows any hydrogen-containing compound to act as an acid through proton transfer.
3) The Lewis concept further expands the definition of acids and bases to include compounds without hydrogen, such as AlCl3 acting as an acid and Na2CO3 acting as a base by accepting or donating electron pairs.

Acids, bases and salt
This document defines acids, bases, and salts according to three theories:
1) Arrhenius defines acids as substances that yield hydrogen ions in water and bases as substances that yield hydroxide ions in water. Neutralization produces salt and water.
2) Bronsted-Lowry defines acids as proton donors and bases as proton acceptors. Neutralization involves the transfer of a proton from an acid to a base.
3) Lewis defines acids as electron pair acceptors and bases as electron pair donors. Neutralization involves the sharing of an electron pair between an acid and base.

- Hard acids prefer to interact with hard bases that have donor atoms like N, O, F, while soft acids prefer soft bases with donor atoms like P, S, Se, Cl, Br.
- Examples of hard acids are H+, Li+, Na+, K+ and hard bases are OH-, F-. Soft acids include Cu+, Ag+, Au+ and soft bases include S2-, Se2-.
Acids-bases-salts-VG.ppt
The document discusses acids, bases, and salts. It provides information on the Arrhenius and Bronsted-Lowry theories of acids and bases. Key points include: Arrhenius acids contain H+ ions and bases contain OH- ions. Bronsted-Lowry defined acids as proton donors and bases as proton acceptors. Acids have a pH below 7 while bases are above 7. Neutralization reactions involve acids and bases reacting to form water and a salt. Titration can be used to determine the concentration of an unknown acid or base solution.
Acid base and acid base titration
This chapter discusses acids and bases according to the Arrhenius and Brønsted-Lowry definitions. The Arrhenius definition states that acids are substances that produce hydronium ions (H3O+) in water and bases produce hydroxide ions (OH-). Brønsted-Lowry defines acids as proton donors and bases as proton acceptors. Both definitions are discussed along with their advantages and limitations. Strong and weak acids/bases are compared based on their extent of ionization in water. Neutralization reactions between acids and bases are outlined. Conjugate acid-base pairs are introduced in the context of Brønsted-Lowry acid-base reactions. Certain substances, called

This document discusses salt hydrolysis and buffer solutions. It explains that salt hydrolysis occurs when the cation or anion of a salt reacts with water, producing acidic or basic solutions depending on the relative strengths of the products. There are four types of salt hydrolysis based on the salt containing strong/weak acids and bases. Buffer solutions resist pH changes upon adding acids or bases. They work by containing a weak acid and its conjugate base or weak base and conjugate acid. Common examples are discussed along with the Henderson-Hasselbalch equation for calculating buffer pH.

4.2 acids and bases
This document discusses acids and bases according to the Arrhenius and Brønsted-Lowry theories. It defines acids as substances that produce hydrogen ions (H+) or donate protons in water according to Arrhenius, and substances that donate protons according to Brønsted-Lowry. Bases are defined as substances that produce hydroxide ions (OH-) in water according to Arrhenius, and substances that accept protons according to Brønsted-Lowry. Examples of strong and weak acids and bases are given. The limitations of the Arrhenius theory and the concept of conjugate acid-base pairs are also outlined.
Acid base concepts
This document discusses different theories of acids and bases:
1) Arrhenius theory defines acids as substances that produce H+ ions in aqueous solution and bases as substances that produce OH- ions. Neutralization occurs via reaction of H+ and OH- to form H2O.
2) Bronsted-Lowry theory defines acids as proton donors and bases as proton acceptors. Acid-base reactions involve proton transfer.
3) Lewis theory defines acids as electron pair acceptors and bases as electron pair donors. Lewis acid-base reactions involve sharing of electron pairs to form adducts. Common examples include formation of hydronium ion and metal-ligand complexes.
Acid Base -Part 2-.pptx
This document discusses different types of hydrolysis reactions and provides examples of acid-base titrations. It describes salt, acid, and base hydrolysis reactions. For acid-base titrations, it explains that a strong acid titrated with a strong base will have a high starting pH declining to 7 at the equivalence point then continuing to a low pH. It also discusses using pH meters and acid-base indicators to determine the equivalence point.
Acid, base and salt wasi
An acid is defined as a substance that yields hydrogen ions in water, while a base yields hydroxide ions. The Arrhenius theory defines acids and bases in terms of their dissociation in water, but it is limited to aqueous solutions and does not account for bases like ammonia without hydroxide groups. Lewis expanded the definitions to include any species that can accept or donate electron pairs. Acids and bases can be strong or weak depending on how fully they dissociate in water, yielding more or fewer hydrogen or hydroxide ions. A salt is formed when an acid is neutralized by a base through ionic bonding, and salts exist as neutral or acidic/basic depending on remaining hydrogen or hydroxide
body fluids (water, acid, base and buffers).pptx
Water is a polar molecule made of two hydrogen atoms bonded to one oxygen atom in a covalent bond. It has many unique properties including being a universal solvent, having high surface tension and specific heat, and exhibiting strong cohesion and adhesion. These properties arise from water's polar nature and hydrogen bonding between water molecules. Buffers help maintain pH and resist changes upon addition of acids or bases through acid-base reactions between their components. The body maintains pH levels through important buffer systems including bicarbonate, phosphate, and proteins that buffer cellular fluids and blood.
Amphiprotic. The preferred term is amphoteric. A .pdf
Amphiprotic. The preferred term is amphoteric. A compound that is amphoteric can
behave as either an acid or a base. These are most commonly explained when using the
Bronsted-Lowry theory of acids and bases. Sorry. NONE of these are amphoteric (or
amphiprotic). In order to behave as a Bronsted-Lowry acid it must donate a proton. That
narrows it down to HCl and HSO4-. In order to behave as a base it must accept a proton. A, D
and E can all accept protons. HCl is a strong acid and dissociates to form H+ and Cl-. There is
no tendency to gain a proton. HSO4- is a weak acid and can donate a proton, but it won\'t accept
a proton to make H2SO4 because H2SO4 is a strong acid and completely dissociates. Even if
one of the choices had been HSO3- we would still have a problem. It would be tempting to say
that HSO3- could gain a proton to make the weak acid H2SO3. The problem is that H2SO3 does
not exist in aqueous solution. It is a fictitious acid, much like H2CO3 which also cannot exist in
aqueous solution. The bottom line is that NONE of these are amphoteric. ========= Follow

H2SO4 is a strong acid and completely dissociates to form H+ and HSO4-. The H+ will combine
with OH- to make water, and you\'re right back where you started. No. HSO4- is NOT

about the physical state?\" No. For the substance to gain a proton, it will be in aqueous solution.

2. Acids and bases can be strong or weak depending on their degree of dissociation. Strong acids and bases fully dissociate while weak ones only partially dissociate.
3. Acid-base titrations involve neutralizing an acid with a base. The pH changes during titration depend on whether the acid and base are strong or weak. Indicators are used to detect the endpoint of titration.

1.The pozzolanic reaction is the chemical reaction that occurs in .pdf
1.
The pozzolanic reaction is the chemical reaction that occurs in portland cement upon the addition
of pozzolans. It is the main reaction involved in the Roman concrete invented in Ancient Rome
and used to build, for example, the Pantheon. The pozzolanic reaction converts a silica-rich
precursor with no cementing properties, to a calcium silicate, with good cementing properties.
In chemical terms, the pozzolanic reaction occurs between calcium hydroxide, also known as
portlandite (Ca(OH)2), and silicic acid (written as H4SiO4 or as Si(OH)4):
Ca(OH)2 + H4SiO4 CaH2SiO4·2 H2O
or summarized in abbreviated notation of cement chemists:
CH + SH C-S-H
The product CaH2SiO4·2 H2O is a calcium silicate hydrate, also abbreviated as C-S-H in cement
chemist notation, the hyphenation denotes the variable stoichiometry. The ratio Ca/Si, or C/S,
and the number of water molecules can vary and the above-mentioned stoichiometry may differ.
Many pozzolans may also contain aluminate, or Al(OH)4, that will react with calcium hydroxide
and water to form calcium aluminate hydrates such as C4AH13, C3AH6 or hydrogarnet, or in
combination with silica C2ASH8 or strätlingite (cement chemist notation). In the presence of
anionic groups such as sulphate, carbonate or chloride, AFm phases and AFt or ettringite phases
can form.
slag reaction
The reaction of slag in cement with and without interaction with the clinker hydration is
extensively discussed in previous works of the current authors (/4/,/5/) and is briefly reviewed
here. The hydration products of slag are principally the same as those identified in hydrating
Portland cement paste, with the additional presence of a hydrotalcite-like phase. The composition
of the main hydration product, C-S-H, however, is obviously influenced by the presence of slag,
and is thus different from that in hydrating Portland cement paste. It is marked by a relatively
lower C/S ratio and the high contents of A substituting for S in the bridging tetrahedral of a
dreierkette structure /12/. The substitution degree is dependent on the C/S ratio of C-S-H and
also the amount of A available for substitution /12/. The reaction of pure slag (alkali-activated) is
written as:
2.
Since fly ash particles are spherical and in the same size range as portland cement, a reduction in
the amount of water needed for mixing and placing concrete can be obtained. In precast concrete,
this can be translated into better workability, resulting in sharp and distinctive corners and edges
with a better surface appearance. This also makes it easier to fill intricate shapes and patterns.
Fly ash also benefits precast concrete by reducing permeability, which is the leading cause of
premature failure. The use of fly ash can result in better workability, pumpability, cohesiveness,
finish, ultimate strength, and durability. The fine particles in fly ash help to reduce bleeding and
segregation and improve pumpability and finishing, especially in lean mixes.

Gram-negative bacteria. It is the precursor of mitochondria. Bacteria belonging to this group
consist of all kind of nutritional types.This phylum further divided into classes of alpha, beta,
gamma, delta, epsilon where alpha- proteobacteria belongs to purple non sulfur bacteria; beta-
proteobacteria belongs to versatile metabolically active bacteria i.e. chemolithoautotrophs,
photoautotrophs, and general heterotrophs; gamma proteobacteria belongs to economically
important bacteria, such as the E. coli, pathogenic bacteria, methane oxidizers as well, ;delta
mainly belongs to those bacteria which cary out sulfur cycle in anaerobic conditions.
2. two phylas are: planctomycetes and bacteroidetes. Bacteroidetes are associated with both
organic as well as GMO roots while planctomycetes is more abundant in GMO root.
3. GMO roots are those which carry a foreign gene in its genome as a result the chemicals or
other metabolites produced by GMO root is different from the organic root. That is why the
bacterial community is different in GMO root and organic root.
4. Whole genome squencing or pyrosequencing can be done to identify and confirm the bacterial
communities present or associated with organic roots as well as GMO roots.

Acid and base theories
This document discusses acids and bases. It begins by defining the objectives of understanding acid and base definitions and theories. It then provides examples of common household and laboratory acids and bases. Next, it explains the Arrhenius theory that acids dissociate in water to form H+ ions and bases dissociate to form OH- ions. It also discusses the Brønsted-Lowry theory that acids donate protons and bases accept protons. Neutralization reactions between acids and bases to form salts and water are then explained. The document concludes by discussing acid-base conjugate pairs and examples.

Acids, bases and salt
This document defines acids, bases, and salts according to three theories:
1) Arrhenius defines acids as substances that yield hydrogen ions in water and bases as substances that yield hydroxide ions in water. Neutralization produces salt and water.
2) Bronsted-Lowry defines acids as proton donors and bases as proton acceptors. Neutralization involves the transfer of a proton from an acid to a base.
3) Lewis defines acids as electron pair acceptors and bases as electron pair donors. Neutralization involves the sharing of an electron pair between an acid and base.

- Hard and soft acids and bases (HSAB) can be classified based on their polarizability - hard species have tightly held electron clouds while soft species have loosely held, easily polarized electron clouds.
- Hard acids prefer to interact with hard bases that have donor atoms like N, O, F, while soft acids prefer soft bases with donor atoms like P, S, Se, Cl, Br.
- Examples of hard acids are H+, Li+, Na+, K+ and hard bases are OH-, F-. Soft acids include Cu+, Ag+, Au+ and soft bases include S2-, Se2-.
Acids-bases-salts-VG.ppt
The document discusses acids, bases, and salts. It provides information on the Arrhenius and Bronsted-Lowry theories of acids and bases. Key points include: Arrhenius acids contain H+ ions and bases contain OH- ions. Bronsted-Lowry defined acids as proton donors and bases as proton acceptors. Acids have a pH below 7 while bases are above 7. Neutralization reactions involve acids and bases reacting to form water and a salt. Titration can be used to determine the concentration of an unknown acid or base solution.
Acid base and acid base titration
This chapter discusses acids and bases according to the Arrhenius and Brønsted-Lowry definitions. The Arrhenius definition states that acids are substances that produce hydronium ions (H3O+) in water and bases produce hydroxide ions (OH-). Brønsted-Lowry defines acids as proton donors and bases as proton acceptors. Both definitions are discussed along with their advantages and limitations. Strong and weak acids/bases are compared based on their extent of ionization in water. Neutralization reactions between acids and bases are outlined. Conjugate acid-base pairs are introduced in the context of Brønsted-Lowry acid-base reactions. Certain substances, called

This document discusses salt hydrolysis and buffer solutions. It explains that salt hydrolysis occurs when the cation or anion of a salt reacts with water, producing acidic or basic solutions depending on the relative strengths of the products. There are four types of salt hydrolysis based on the salt containing strong/weak acids and bases. Buffer solutions resist pH changes upon adding acids or bases. They work by containing a weak acid and its conjugate base or weak base and conjugate acid. Common examples are discussed along with the Henderson-Hasselbalch equation for calculating buffer pH.

4.2 acids and bases
This document discusses acids and bases according to the Arrhenius and Brønsted-Lowry theories. It defines acids as substances that produce hydrogen ions (H+) or donate protons in water according to Arrhenius, and substances that donate protons according to Brønsted-Lowry. Bases are defined as substances that produce hydroxide ions (OH-) in water according to Arrhenius, and substances that accept protons according to Brønsted-Lowry. Examples of strong and weak acids and bases are given. The limitations of the Arrhenius theory and the concept of conjugate acid-base pairs are also outlined.
Acid base concepts
This document discusses different theories of acids and bases:
1) Arrhenius theory defines acids as substances that produce H+ ions in aqueous solution and bases as substances that produce OH- ions. Neutralization occurs via reaction of H+ and OH- to form H2O.
2) Bronsted-Lowry theory defines acids as proton donors and bases as proton acceptors. Acid-base reactions involve proton transfer.
3) Lewis theory defines acids as electron pair acceptors and bases as electron pair donors. Lewis acid-base reactions involve sharing of electron pairs to form adducts. Common examples include formation of hydronium ion and metal-ligand complexes.
Acid Base -Part 2-.pptx
This document discusses different types of hydrolysis reactions and provides examples of acid-base titrations. It describes salt, acid, and base hydrolysis reactions. For acid-base titrations, it explains that a strong acid titrated with a strong base will have a high starting pH declining to 7 at the equivalence point then continuing to a low pH. It also discusses using pH meters and acid-base indicators to determine the equivalence point.
Acid, base and salt wasi
An acid is defined as a substance that yields hydrogen ions in water, while a base yields hydroxide ions. The Arrhenius theory defines acids and bases in terms of their dissociation in water, but it is limited to aqueous solutions and does not account for bases like ammonia without hydroxide groups. Lewis expanded the definitions to include any species that can accept or donate electron pairs. Acids and bases can be strong or weak depending on how fully they dissociate in water, yielding more or fewer hydrogen or hydroxide ions. A salt is formed when an acid is neutralized by a base through ionic bonding, and salts exist as neutral or acidic/basic depending on remaining hydrogen or hydroxide
body fluids (water, acid, base and buffers).pptx
Water is a polar molecule made of two hydrogen atoms bonded to one oxygen atom in a covalent bond. It has many unique properties including being a universal solvent, having high surface tension and specific heat, and exhibiting strong cohesion and adhesion. These properties arise from water's polar nature and hydrogen bonding between water molecules. Buffers help maintain pH and resist changes upon addition of acids or bases through acid-base reactions between their components. The body maintains pH levels through important buffer systems including bicarbonate, phosphate, and proteins that buffer cellular fluids and blood.
Amphiprotic. The preferred term is amphoteric. A .pdf
Amphiprotic. The preferred term is amphoteric. A compound that is amphoteric can
behave as either an acid or a base. These are most commonly explained when using the
Bronsted-Lowry theory of acids and bases. Sorry. NONE of these are amphoteric (or
amphiprotic). In order to behave as a Bronsted-Lowry acid it must donate a proton. That
narrows it down to HCl and HSO4-. In order to behave as a base it must accept a proton. A, D
and E can all accept protons. HCl is a strong acid and dissociates to form H+ and Cl-. There is
no tendency to gain a proton. HSO4- is a weak acid and can donate a proton, but it won\'t accept
a proton to make H2SO4 because H2SO4 is a strong acid and completely dissociates. Even if
one of the choices had been HSO3- we would still have a problem. It would be tempting to say
that HSO3- could gain a proton to make the weak acid H2SO3. The problem is that H2SO3 does
not exist in aqueous solution. It is a fictitious acid, much like H2CO3 which also cannot exist in
aqueous solution. The bottom line is that NONE of these are amphoteric. ========= Follow

1.The pozzolanic reaction is the chemical reaction that occurs in .pdf
1.
The pozzolanic reaction is the chemical reaction that occurs in portland cement upon the addition
of pozzolans. It is the main reaction involved in the Roman concrete invented in Ancient Rome
and used to build, for example, the Pantheon. The pozzolanic reaction converts a silica-rich
precursor with no cementing properties, to a calcium silicate, with good cementing properties.
In chemical terms, the pozzolanic reaction occurs between calcium hydroxide, also known as
portlandite (Ca(OH)2), and silicic acid (written as H4SiO4 or as Si(OH)4):
Ca(OH)2 + H4SiO4 CaH2SiO4·2 H2O
or summarized in abbreviated notation of cement chemists:
CH + SH C-S-H
The product CaH2SiO4·2 H2O is a calcium silicate hydrate, also abbreviated as C-S-H in cement
chemist notation, the hyphenation denotes the variable stoichiometry. The ratio Ca/Si, or C/S,
and the number of water molecules can vary and the above-mentioned stoichiometry may differ.
Many pozzolans may also contain aluminate, or Al(OH)4, that will react with calcium hydroxide
and water to form calcium aluminate hydrates such as C4AH13, C3AH6 or hydrogarnet, or in
combination with silica C2ASH8 or strätlingite (cement chemist notation). In the presence of
anionic groups such as sulphate, carbonate or chloride, AFm phases and AFt or ettringite phases
can form.
slag reaction
The reaction of slag in cement with and without interaction with the clinker hydration is
extensively discussed in previous works of the current authors (/4/,/5/) and is briefly reviewed
here. The hydration products of slag are principally the same as those identified in hydrating
Portland cement paste, with the additional presence of a hydrotalcite-like phase. The composition
of the main hydration product, C-S-H, however, is obviously influenced by the presence of slag,
and is thus different from that in hydrating Portland cement paste. It is marked by a relatively
lower C/S ratio and the high contents of A substituting for S in the bridging tetrahedral of a
dreierkette structure /12/. The substitution degree is dependent on the C/S ratio of C-S-H and
also the amount of A available for substitution /12/. The reaction of pure slag (alkali-activated) is
written as:

Since fly ash particles are spherical and in the same size range as portland cement, a reduction in
the amount of water needed for mixing and placing concrete can be obtained. In precast concrete,
this can be translated into better workability, resulting in sharp and distinctive corners and edges
with a better surface appearance. This also makes it easier to fill intricate shapes and patterns.
Fly ash also benefits precast concrete by reducing permeability, which is the leading cause of
premature failure. The use of fly ash can result in better workability, pumpability, cohesiveness,
finish, ultimate strength, and durability. The fine particles in fly ash help to reduce bleeding and
segregation and improve pumpability and finishing, especially in lean mixes.

electronegativities of Li and F. F is much more electronegative, and will have a lot of the
electron density around it, whereas Li will have much less. (In fact LiF is considered an ionic
compound with Li+ and F-.)

What inequities exist in health care?
If you take the question from the perspective of \"access to health care\", inequalities are usually
split in the literature on spatial and non-spatial factors.
Into space factors, because they put distance between the supply of health services and the
people who claim we can find:
Then, non spacial factors as:
When there is inequality in access to health care, do you think this is a problem of justice or
something else?
I think that inequalities in our society are reflected in the health system, for example, is not in
poor neighborhoods may not have good hospitals, it is that people think that the poor do not
deserve good hospitals. Something similar occurs with certain diseases stigmatized as AIDS or
sexually transmitted diseases, protocols and supply health is contaminated by prejudice, so the
real struggle lies in advance eliminate prejudices in society at large and not just within the health
system.
Do you consider it fair for all age groups to possess equal access to health care providers?
I think they should prioritize vulnerable groups, infants, children, pregnant women, people with
disabilities, chronic diseases and seniors, they must direct the bulk of the resources, and others
allow access as their ability to pay, allowing that those who have resources to pay for their health
and that have not to be supported.
What are some of the unintended consequences of Affordable Care Act and what would you
recommend?
The main criticism has been that it has forced insurers to provide a minimum package to those
who have historically been excluded, either preexisting, economic, inmigration status or
employment conditions. Insurers have argued that this regulation raises their operating costs
considerably and inevitably fall in the rest of the insured, increasing the price of their plans.
On the other hand, it has been much criticized lack of planning and implementation capacity that
has taken the state to meet the entire demand of applicants that has befallen them.
I think both issues are coordinated, to the extent that public policy makers will come up against
obstacles, should have the ability to learn to overcome them on the go.

The tops for collecting network based evidenceyou think that your.pdf
The tops for collecting network based evidence:
you think that your organization’s system has been attacked, or maybe an insider is emailing
your organization’s trade secrets to a friend at a rival corporation. What should you do? The
single most helpful network-based incident response activity is to deploy computer systems that
do nothing but intercept or collect network communications. Capturing network communications
is a critical and necessary step when investigating alleged crimes or abuses.
In this chapter, we will demonstrate how to capture network traffic the ugly and bare-metal way,
with software such as tcpdump and WinDump. We will discuss how to assemble a robust,
secure, network-monitoring system and conduct full-content monitoring of network traffic.
Catching the traffic is only a portion of the work; extracting meaningful results is the other
challenge. After you have collected the raw data that composes your network-based evidence,
you must analyze that data. The analysis of network-based evidence includes reconstructing the
network activity, performing low-level protocol analysis, and interpreting the network activity.
We will introduce the tools that you can use to analyze the data .If a law enforcement officer
suspects an individual of a crime such as minor drug dealing, the suspect is usually placed under
surveillance to confirm suspicions, accumulate evidence, and identify co-conspirators. The same
approach works with suspected crimes against computer networks. Network monitoring is not
intended to prevent attacks. Instead, it allows investigators to accomplish a number of tasks
Network monitoring can include several different types of data collection: event monitoring,
trap-and-trace monitoring, and full-content monitoring. When responding to computer security
incidents, you will likely rely on collecting full-content data with tools such as tcpdump.
However, there may be occasions when you will intercept solely the transactional data with a
trap-and-trace. Event monitoring is based on rules or thresholds employed on the network-
monitoring platform. Events are simply alerts that something occurred on your network.
Traditional events are generated by a network IDS, but events can also be created by network
health monitoring software like MRTG (Multi Router Traffic Grapher) or NTOP.
Noncontent monitoring records the session or transaction data summarizing the network activity.
Law enforcement refers to such noncontent monitoring as a pen register or a trap-and-trace. It
typically includes the protocol, IP addresses, and ports used by a network communication.
Additional data may include flags seen during the conversation (if TCP is used), counts of bytes
of information sent by each side, and counts of packets sent by each side.
Session data does not care about the content of a conversation. Here is a sample of session data,
generated by tcptrace.
Full-content monitoring yields data that includes the raw packets collected fr.

- 1. Sulfuric acid (H2SO4) is the catalyst for the reaction. Sulfuric acid will dissociate in solution to give H+ and HSO4-. The H+ will start the reaction. The 1-hexene's double bond will attack the H+ (proton) and then a carbocation will form. The MOST stable carbocation will form and here you have a choice between a primary and secondary carbocations. The more substituted a carbocation is then the more stable it will be and therefore the secondary carbocation forms. H2O (water) which is the solvent and the nucleophile will attack the carbocation. The intermediate species will have a formal charge of +1 and will lose a H+ (proton) to give a neutral species. The reaction is called acid catalyzed hydration of alkenes.
