Reflection Of Consumer Chemistry
INTRODUCTION: Nowadays, people here in this world are using science in their everyday lives.
When you fry a fish, there's a science. When you wash your clothes, there's a science behind it.
Everything is science. There are different branches of science. Including Biology, Botany, Zoology,
and many more. But one of the most used in everyday life in the branches of science is the
CHEMISTRY. It is a branch of physical science that deals with composition, structure, properties
and changes of matter. Chemistry is the one who is responsible for photosynthesis (plants making
food for their own). But Consumer chemistry is the one that deals with humans in our everyday
lives. Consumer Chemistry is the branch of Chemistry that makes consumable products. Consumer
chemistry deals with food, cosmetics, fertilizers ... Show more content on Helpwriting.net ...
I've learned mny topics in Consumer Chemistry but one of the mot important lesson and the hardest
(for me) is the Redox or Oxidation–Reduction Reaction. Why is it the hardest topic for me? Well, at
first, while our teacher was discussing this, I thought that this lesson is pretty easy because I
understand all her lessons and I had no problem absorbing the lessons. Butwhen the day after comes,
I was already confused on how to do the Redox. I tried to approach my classmates who are great in
Consumer Chemistry. But I always forget it after that and got confused again. And I think, that's the
reason I got a very low score on our summative test. After that test, I promised to myself that I will
strive hard for me to get a high score on our periodical test. That's why I made this learning module,
to help me and others who are having a hrd time on

Introduction: The periodic table is the most important chemistry reference there is. It arranges all the
known elements in an informative array. Just like when entering a grocery store similar items are
grouped together which makes an item easier to find. Elements are arranged left to right and top to
bottom in order of increasing atomic number. The different rows of elements are called periods. The
period number of an element signifies the highest energy level an electron in that element occupies.

Helium: Periodic Table Of Elements
Helium is an element. It is in the first period, in group 8 in the periodic table of elements. Helium is
also a nonmetal. Its element symbol is He, and it has an atomic number of 2, and an atomic mass or
molar mass of 4.003 amu. This means that helium contains 2 protons, 2 electrons, and 2 neutrons.
Helium is the second most common element on the universe. Helium is a noble gas, a noble gas is a
substance that does not have color, taste or odor, and they are not flammable. Noble gases were
originally labeled as group 0 in the periodic table because once they were discovered they believed
that they were not able to bond to any other atoms, meaning that they weren't able to combine with
other elements to be able to form chemical compounds. Now they have discovered that some noble
gases do form compounds. [1] Helium was discovered by some astronomers named, Pierre Janssen
and Norman Lockyer. Pierre was studying the suns spectrum when he noticed a yellow line. Later
Norman discovered that the line could not be produced by any elements they had known in that
time. Noticing that a new element was formed that came from the suns spectrum. [4] ... Show more

But we are using helium so much that we are using more helium that is being produced, so there are
new technologies that are trying to find ways to recycle helium to slow down the problem. There are
times that the balloon you inflated with helium begins to sink, that is because the helium can leak
from the balloon. Helium is less dense than normal air, so at times when people inhale it causes their
voice to change becoming higher than normal. Helium is a gas but can turn from liquid to solid,
there just needs to be a temperature of absolute zero. When helium is liquid it is used to cool some
metals for superconductivity use. [4] Those are some fun facts on

Interpreting The Periodic Table At The Middle Of The...
Interpreting the periodic Table Lab partner's name: Priscila Baque Scarleth Romero Jilyan Carrera
Date: 01–05–14 1. Introduction: Imagine the confusion among chemists during the middle of the
nineteenth century. By 1860, more than 60 elements had been discovered. Chemists had to learn the
properties of these elements as well as those of the many compounds that they formed a difficult
task. And to make matters worse, there was no method for accurately determining an element's
atomic mass or the number of atoms of an element in a particular chemical compound. Different
chemists used different atomic masses for the same elements, resulting in different compositions
being proposed for the same compounds. This made it nearly impossible for one chemist to
understand the results of another. Everything around us is made of atoms. Most objects are mixtures
or compounds of different types of atoms, but some common items consist of only a single type of
atom. Each image here represents a common item that is composed of only one or a few elements.
Pennies were once made of just one element copper. Today, zinc is also a major component of
pennies. If we could look very closely at a copper penny, we would see that every atom is the same.
Typically, items in stores have been arranged so that it is easy to find what you are looking for, and
similar products are usually grouped together. This makes finding an item simpler than if the items
were just thrown

In some instances lead reacted very similarly with the alkaline earth metal but very different in the
other reactions such as with iodide. This is due to lead's position on the periodic table as compared
to those of the alkaline earth metals. The position on the periodic table correlates to an element's
atomic radius, ionization energy, and electron affinity. All of these properties affect an element's
chemical properties such as solubility. A systematic error occurred during my experiment when I
observed a reaction between barium and iodide. There should have been no reaction. This error is
probably the result of using a test tube that was not cleaned properly prior to combining Ba(NO3)2
with NaI. This experiment reinforced the concepts introduced in Chapter 8 of our textbook. Pre–Lab

The activity was separated into 4 parts concerning 5 different groups of elements. In the first part,
we had identified the physical state, the color, and the solubility in water of the Carbonates of I–A
and II–A Elements. The elements Na2 Co3, Li2 CO3, Mg CO3, Ca CO3 had a powdery appearance
while Ba CO3 had a ball shape appearance and K2 CO3 had a wet, granule appearance. All of the
elements stated have a white color. The elements Na2 Co3, Li2 CO3, K2 CO3 were soluble to water
while Mg CO3 Ca CO3 Ba CO3 were not. For the second part, we had identified the physical state
and the color of some of the Group IV–A Elements. Carbon had a powdery appearance and it is

Lead has a ball shaped appearance and it is gray in color. For the third part, we had a group of
elements, Group II–A Metal Oxides, undergo the litmus paper test and identified its chemical
equation. MgO,CaO ,BaO all had the same results on the test, with all having Red → Blue, Blue →
Blue results resulting having almost the same chemical equations with MgO having MgO + H2O →
Mg(OH)2 , CaO having CaO + H2O → Ca(OH)2 and BaO having Ba + H2O → Ba(OH)2. As for
the last part, we had a different group of elements, Group V–A Nonmetal Oxides, undergo the litmus
paper test and identified its chemical equation. The elements P2O5, Sb2O3 did not undergo any
change so there is no need for a chemical equation while Nitric acid + Copper changed color from
blue to red so it's chemical equation is 4HNO3 + Cu → Cu(NO3)2 + 2H2O +

Using P–element Induced Male Recombination to Generate a Deletion in the DMAP1 Gene on
Chromosome Two in Drosophila melanogaster
Abstract: The goal of this study was to induce a deletion in the DMAP1 gene on chromosome two in
Drosophila melanogaster through P–element mobilization. The DMAP1 gene may be an essential
gene, however not much is known about it. We attempted to uncover the function of DMAP1 by
creating a series of genetic crosses and selecting for brown–eyed non–stubble male flies that may
have the deletion. To test whether these flies had the deletion, we produced PCR products and ran
them on an agarose gel, which resulted as inconclusive. We created a balanced stock of flies
homozygous for the deletion to see if the ... Show more content on Helpwriting.net ...
For example, wings–clipped P–elements that lack the inverted repeats (not able to be mobilized
themselves), which are not internally deleted and can produce a transposase source, can be
introduced to the internally–deleted P–element to provide transposase and therefore allow
transposition to occur. The provided transposase recognizes and binds to inverted repeats on the
internally–deleted P–element, which introduces nicks in the DNA beside the inverted repeats. This
allows the element to excise and insert into a new location. If it excises neatly out of the DNA, a
deletion will not occur. However, if it excises to a homologue towards the right or the left, due to an
error in the excision process, a deletion will occur through this pre–meiotic recombination event.
This process of P–element mobilization is the basis of how we directed recombination in male flies,
and therefore the basis of generating deletions in the DMAP1 gene. We made several crosses that
allowed P–element mobilization to occur in male flies by crossing P–element strains (non–
autonomous) to a transposase source, producing heterozygous flies containing a P–element and a
transposase source, and therefore allowing us to induce and detect male recombination events in
progeny. The specific recombination event of interest is when the P–element is mobilized towards
the right onto a homologue, which may have induced a deletion in

The purpose of the lab was to mimic the way Mendeleev placed the elements on the periodic table.
Mendeleev was a Russian chemist who produced the first orderly periodic table. Frist, the way the

Second, the objectives are observeing the physical states of common elements, and the progression
of the periodic table, lastly speculate by determining the unknown elements established on the

protons and neutrons, and the shells (orbitals) in which electrons are present, were they orbit around
the positively charged nucleus to create a neutral atom. The Atoms are thus made up of three
subatomic particles: The proton, neutrons and electrons. The protons are positively charged while
the electrons are negatively charged, and the neutrons are neutral.

In a lab, when one performs a titration it is mainly performed few times, but the same procedure is
carried out also in industry but in large quantities and not just few titrations but many. The procedure
is mainly the same but in industry one needs to find a balance between precision and speed, one way
to reduce time–wasting is that when preparing a standard solution instead of using a burette, one
weighs the liquids so as to quicken the process.
One may also find automatic titrations apparatus in more advance labs which prepares both the
standard solution as well as performs the titrations with accurate results. Also in industry to further
increase the speed and also the accuracy, when preparing standard solutions, one may use a Gilson
Pipette which works by setting the amount of volume which needs to be extracted from the solution
and by pressing a lever, the exact volume is taken and transferred. This technique takes the use of
the bulb pipette, because it's easier to use and more precise when working with small

TE-5 Essay
In this study, TE–5 doses of 0.04, 0.4, 0.12, and 4 ml/kg (a dose calculated to be appropriate for a
subject, 10 times the appropriate dose, 30 times the appropriate dose, and 100 times the appropriate
dose) were administered to rats in order to examine the effects on the elemental levels and blood
properties of the living organisms, and to evaluate the safety of TE–5 doses with regards to an
organism's homeostasis. First off, iron is excreted from the body mainly via bile and the intestinal
absorption system. (12) In this experiment, even in very low TE–5 dose groups, remarkable changes
in the iron content of tissue was not observed, which can probably be blamed on iron excretion via
bile corresponding to the dosage of TE–5 which ... Show more content on Helpwriting.net ...
On the other hand, extracorporeal excretion of zinc is mainly carried out via pancreatic liquid as is
known to play a role in the homeostasis of zinc in the body. In this experiment, rapid changes in zinc
content in the tissue were not observed, even in the dose groups up to 1.2 ml / kg. This suggests that
pancreatic fluid effectively excreted zinc when the dose of TE–5 was 1.2 ml / kg or lower. The liver
plays a central role in copper homeostasis and can be said to be the most important organ involved
in storage, blood transport, protein ceruloplasmin production, and bile duct excretion. (17, 18, 19)
Also, in this experiment, no significant increase in the copper content in the liver was observed,
even in the 1.2 dose group (30 times adult regular dose) This is because copper is excreted in the
bile duct and does not get reabsorbed like iron. Excreted copper does not return to the liver. Also, in
the 4 dose group (100 times the adult regular dose) a marked rise in copper content was observed in
the liver, spleen, kidney, and tibia, probably because at this dose, copper homeostasis failed.
Manganese has a low toxicity (12), but chronic manganese poisoning is often reported, such as with

Can you believe that in 1869 Russian Chemist Dimitri Mendeleev arranged the chemical elements
by atomic mass and started the development of the periodic table. After this Henry Gwyn Moseley
was an English Physicist and Developed Mosley's which sorted the chemical elements of the
periodic table in a logical order based on physics. Before all the naturally occurring elements were
discovered the periodic table was used to predict chemical and physical properties of elements in the
gaps of the table. The periodic table can now be used to predict properties of elements yet to be

The Transition metals are the 38 elements between groups 3 and 12. Along with all metals, these
transition elements are ductile, malleable, and conduct electricity and heat. Their valence electrons
are used to combine with other elements that are present in one shell. The element we are going to
look at from this group is Beryllium. This element has the symbol of Be and has the atomic number
of 4. It is created through stellar nucleosynthesis and is a rare element. It is a gray–metallic color

The Periodic Table : Potassium, Sulfur, And Krypton
The Periodic Table contains 118 elements, all different with shape, size, and what it's made up of.
Out of the 118, 3 were chosen and they will be discussed later in this paper. Those elements are
Potassium, Sulfur, and Krypton.
The first is Potassium. Potassium was first discovered and isolated by Sir Humphrey Davy, a
Cornish chemist and inventor, in 1807. Potassium is highly reactive, but Davy isolated the element
through a process what's called electrolysis, a process by which an electric current is passed through
the element to cause chemical change within the element. Potassium could be extracted through
minerals such as carnalite, langbeinite, and polyhalite minerals. Potassium is also found in the
Earth's crust, and makes up around 1.5 to 2% of the Earth's crust. Potassium also can't be found in
nature as a free element. Potassium is atomic number 19 in the periodic table and is symbolized as
the letter "K" in the periodic table. The element is in Group 1, Period 4 on the periodic table. The
element is an alkali metal and has somewhat of silver color to the element. The structure of the
element has a cubic shape at room temperature and has a density of 0.862 g/cm
Elnaka 2 cubed. The melting and boiling point of the element are 63.65 °C (146.57 °F) for melting
and 759.0 °C (1398°F) for boiling. The atomic mass of the element is 39.0983 amu (atomic mass

game techniques to teach media theory to undergraduate students. The author provides background
of the content being taught within the classroom and how it is often difficult for students to
understand. Therefore the use of gaming techniques is used to improve students' performance.

The experimental group used traditional didactic methods with a gamification element at the end of
instruction in the form of an app. The control group just used didactic methods. Through coding and

conclude that gamification has positive effects, however those effects are dependent on the
gamification elements being implemented, and the users using it. Searches through databases
uncovered a growing number of papers on gamification topics over the last decade. Altogether the

Chalcogen Essay
Also known as the oxygen family, chalcogens are sulfur (S), selenium (Se), tellurium(Te), and
polonium (Po). Oxygen (O) is also in group 16, where chalcogens are located on the periodic table.
While it is defined as a chalcogen, oxygen and oxides are often separated from chalcogens because
its chemical behavior is much different than that of the other elements in the group. The other
elements in the group show similar patterns in their electron configurations resulting in similar
chemical behavior. The name chalcogen means "ore former," derived from the Greek words chalcos:
ore and –gen: formation. An interesting fact is that oxygen is the most abundant element on Earth,
second most in the Atmosphere, and third in the whole universe. It is ... Show more content on

Selenium itself is a nontoxic element, but when made into a compound, it can become very toxic.
For example, Hydrogen selenide is intolerable to humans. Tellurium's name is derived from the latin
word for earth, "tellus". It is very brittle and has a silvery–white appearance. When a human is
exposed to even the smallest amount of Tellurium, they develop "Tellurium breath", which smells
like garlic. It was discovered by Franz Joseph Mδller von Reichenstein, who was a the chief
inspector of mines in Transylvania, but was name by M. Klaproth. Polonium, which is very
poisonous and radioactive, was discovered by Marie Curie. She named it after her native country,
Poland. It is very rare and is made only in small quantities through a nuclear reaction of bismuth. An
interesting fact about polonium is that there actually is no real world use for it, but it can be used as
a poison.

The Chalcogens group of elements is comprised of oxygen, sulfur, selenium, tellurium, and

Why Does Atomic Size Matter
Atomic Size: As you go across periods, atomic mass and number increases because more protons are
added to the nucleus and electrons are added to the outer shell meaning the atoms got heavier. Also
when you go down groups the mass and number increases because like before there are more
protons and electrons added (extra "shells").
Atomic Radius: The distance from the centre of the nucleus to the outermost electron 'shell'. Atomic
size gradually decreases from left to right across a period of elements. More electrons and protons
added. They pull the electrons closer and therefore size decreases. Atomic radius increases as more
electron sublevels added when you go down a group. Electron shielding doesn't let outer electrons to
be attracted to ... Show more content on Helpwriting.net ...
The stronger the bond, the more energy required to break that bond. Melting points vary and do not
generally form a distinguishable trend across or down the periodic table. Metals generally have high
melting points because of the attraction between the metal ions and the electrons which means that
high energy levels are needed to break these bonds. Most non–metals possess low melting points. As
you go down group 7 in the periodic table, the forces increase. This means the melting points
increase as the bonds between molecules get stronger and this is why they go from gas to
liquid/solid. As you go across a period, the melting point of the alkali metals is higher than the non–
metals except carbon and silicon (Group 4 because they exist as network lattice structures meaning
every atom is covalently bonded to another atom) but group 4 has the highest melting point due to
the strength of covalent bonding. The atoms in the element are held together by the attraction of the
nuclei to the delocalised electrons, and as the atom gets bigger the electrons get further away from
the nucleus and the attraction decreases allowing bonds to be broken easier. Lead has a high melting
point even though it's in period 6 because of its 12 coordination structure. Tin however has a
distorted structure and so the bonds are not as strong as

Dalton 's Atomic Theory ( 1803 )
Dalton's atomic theory (1803):
Dalton proposed that all matter is made of atoms (tiny indivisible particles), which cannot be
destroyed. He visualised atoms as a solid particle without a structure. All atoms of an element are
identical in mass and properties. The atoms of one element differ from the atoms of all other
elements in atomic weight. Compounds are combinations of two or more different types of atoms. A
chemical reaction results in the rearrangement of atoms in the reactant and product compounds and
they don 't destroy or create atoms.
Thomson's plum pudding model (1909):
Thomson discovered electron in 1897, which allowed him to develop a new atomic model. In
Thomson 's model, the atom is composed of electrons surrounded by a positively charged fluid
which balances the electrons ' negative charges, like negatively charged "plums" which are
surrounded by a positively charged "pudding". Thomson thought the electrons were positioned
throughout the atom in rotating rings. The atom was also sometimes described to have a "cloud" of
positive charge.
Rutherfordian atomic model (1911):
Rutherford's discovery of the nucleus allowed him to develop a new atomic model, the planetary
model. In this model, the centre of the atom is the nucleus. The nucleus contains most of the mass
and all of the positive charge of the atom. Electrons circle around the nucleus like planets do around
the sun. Positive protons in nucleus and electrons in orbit around nucleus.

Group Trend 2: Ionization Energy
Trend 2: Ionization energy
Group Trend:
(Intro) Ionization energy is the energy required to overcome the attraction of the nuclear charge and
remove an electron from a gaseous atom. The first ionization energy is the energy required to
remove the first valence electron. The energy required to remove the second valence electron is
called the second ionization energy, and so on. When one valence electron is removed, the atom
becomes a 1+ cation. When two valence electron is removed, the atom becomes a 2+ cation, and so
forth. This is where the name ionization energy comes from.

higher first, second, and third ionization energy than element #2, K. ... Show more content on

In any period, the shielding is constant throughout the period because the number of energy level is
the same in a period. Therefore, (#1) Ne with 8 protons or effective nuclear charge has a higher
ionization energy than (#2) Li with 3 protons or effective nuclear charge. The period trend for
ionization energy is that the ionization energy increases from left to right on the periodic table,
because the number of protons or effective nuclear charge increases from left to right while the
shielding is constant. Additionally, (#1) Ne is a noble gas, which always has the highest ionization
energy within each period. It is very hard to remove an electron from a noble gas because noble
gases have a full duet/octet which makes them very stable and non reactive. When an element has a
full duet/octet, the element does not want to gain or lose electrons. Therefore, it is very hard for a
noble gas to lose an electron, which means that it has a very high ionization

3. Place:
Place refers to how an organization will distribute its products or services. It is also known as
distribution, channel, or intermediary. Effective distribution is important in order for the
organization to meet its overall marketing objectives. This consists of the following distribution
strategies:
There are two types of distribution channels; the direct channel and the indirect channel. The direct
distribution consists of the manufacturer distributing the goods or services directly to the consumer.
The indirect distribution involves intermediaries in distributing the goods to the consumer, for
example; manufacturer =>wholesaler=>retailer=>consumer.
In a retail marketing mix, location is very important. The place is part of the biggest investments of
the business person, as it has to be located in an easily reachable location. The more accessible a
place is, the more expensive it is to get it. And also, the location includes the nearest competition.

Mendeleev Lab
Dimitri Mendeleev was considered the first chemist to discover that patterns would become
apparent when elements were classified to their properties. Mendeleev's adjustment of elements was
the one and only due to his idea of leaving blank spaces for elements he believed were undiscovered
in 1869. The purpose of the Mendeleev Lab of 1869 is to use knowledge of the periodic table in
order to identify the undiscovered elements. Ultimately the whole idea is to observe, and draw
conclusions to identify the elements. For instance, observing properties, samples, and trends will
help us learn more about the periodic table also, learn more about the hidden elements of
Mendeleev's Lab. The essential way to assign an element to its unknown lab is by density, physical
state and color. For example the unknown #1 was identified as silicon it's physical state was solid,
the density is 2.33 with a gray pigmentation therefore silicon belongs to the carbon family Group 14,
because silicon and elements of the carbon family have similar behaviors. Another unidentified
element was #4, it's physical state is gas, with a density of 0.00374 and is colorless was
distinguished as krypton which belongs in group 18 as a noble gas. Krypton is known as a noble gas
because scientists have found traces of the gas in the atmosphere. ... Show more content on

element of suspense was through characterization of the old woman. According to the text, the old
woman stated, "I'll think that lemonade is cold enough". "I'll bring you out some and tell you
something else about the house".(4) This is relevant because the lemonade was later to be known as
the reason in the killing of Mr. Waterbury which proves the old woman will strike at any moment.
Through the story the "Right Kind of House" the elements of foreshadowing and characterization
show suspense throughout the story. ... Show more content on Helpwriting.net ...
To begin with, the group of suspense in "The Right Kind of House" is the group of Insanity. The
author wrote, " Waterbury put down the empty glass and licked his lips, he was having trouble
keeping his eyes open, and his head was growing very, very dizzy. "Ugh!", he said, " this lemonade
is bitter"(4). This quote suggests the old woman was hunting down on him. She was insane to kill
him because she thought he was the one whom had killed her son and was trying to find the robbery
stash. The suspense group of insanity in the "Right Kind of House" because the old woman was
insane to find her

Investigating An Element's Group In The Periodic Table
Explain how an element's group in the periodic table can be used to predict its outer shell electrons.
(3 marks) The element's group in the periodic table predicts how many electrons are in it's outer
shell. For example, Sodium is in group 1, and has one electron in its outer shell. For elements in
groups 13–18, the last digit of the group predicts how many electrons in its outer shell. For example,
silicon is in group 14 and has 4 electrons in its outer shell. This does not apply to groups 3–12,
which do not always follow a specific pattern. Each element in the periodic table has a specific
proton (atomic) number. Research an element which has at least two isotopes and provide the
number of protons, neutrons and electrons for each isotope. (You may not choose carbon). (3 marks)

Protium(Hydrogen–1) has 1 proton, 0 neutrons, and 1 electron. Deuterium(Hydrogen–2) has 1
proton, 1 neutron, and 1 electron. Finally, tritium(Hydrogen–3) has 1 proton, 2 neutrons, and 1
electron. Metals are not usually found in their pure elemental form. Explain why (one mark) and
give an example of a metallic ore mined in Australia (one mark). Provide one use for that metal.(1
mark) Metals are not usually found in their pure elemental form, as they are instead found in
compounds. This is because metals are very reactive substances, so they form compounds easily. As
the air around the metals contains oxygen, most metals oxidise to form iron ores. An example of a
metallic ore mined in Australia is iron ore. Iron ore can be used to make steel, which can be used in
building materials and construction. Provide three properties of the metal you chose in question 3.
Explain two of those properties in terms of the metallic bonding model. (3
