Electrons are shared unevenly Electrons are closest to the least electronegatative atom Electrons are hypervalent Electrons are donated from one atom to the other Electrons are shared evenly In a nonpolar covalent bond... Electrons are shared unevenly Electrons are closest to the least electronegatative atom Electrons are hypervalent Electrons are donated from one atom to the other Electrons are shared evenly Electrons are shared unevenly Electrons are closest to the least electronegatative atom Electrons are hypervalent Electrons are donated from one atom to the other Electrons are shared evenly Solution Ans . As a covalent bond is formed with the sharing of the electrons between atoms and not with the donation of electrons from one atom to another . Also , a polar covalent bond has uneven or unequal sharing of electrons due to difference in polarity while a non-polar covalent bond has even or equal sharing of electrons between atoms as there is no difference in polarity . Therefore , in a non-polar covalent bond electrons are shared evenly . .

Many molecules contain bonds that fall between th.pdf
Many molecules contain bonds that fall between the extremes of ionic and covalent
bonds. The difference between the electronegativities of the atoms in these molecules is large
enough that the electrons aren\'t shared equally, and yet small enough that the electrons aren\'t
drawn exclusively to one of the atoms to form positive and negative ions. The bonds in these
molecules are said to be polar, because they have positive and negative ends, or poles, and the
molecules are often said to have a dipole moment. for Eg : HCl molecules, for example, have a
dipole moment because the hydrogen atom has a slight positive charge and the chlorine atom has
a slight negative charge. Because of the force of attraction between oppositely charged particles,
there is a small dipole-dipole force of attraction between adjacent HCl molecules. non-polar
molecule has it\'s electron density shifted by a charged molecule, i.e., if a positively charged
species is brought near a species with an evenly distributed charge, the electrons go towards the
side where the positive species is, and away from the opposite side, creating an artificial dipole.
Eg : a helium atom is perfectly symmetrical. But movement of the electrons around the nuclei of
a pair of neighboring helium atoms can become synchronized so that each atom simultaneously
obtains an induced dipole moment.

How does the formation of an ionic bond differ from the formation of a.docx
How does the formation of an ionic bond differ from the formation of a covalent bond?
How does the formation of an ionic bond differ from the formation of a covalent bond? A. An ionic bond is where one atom transfers at least one electron from another atom in an attempt to fill its electron shell. A covalent bond is when electron are shared between atoms and there is equality between atoms in relation to their electrons. B. Ionic bonds form by the transfer of electrons. Covalent bonds form by sharing electrons. In ionic bonding, electrons are completely transferred from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. Ions that have a positive charge are called cations and the ones that have a negative charge are called anions. On the other hand, covalent bonds can be formed by any equal or unequal sharing of electrons. The substances formed by ionic bonds are called compounds and those formed by covalent bonds are referred to as molecules. C. The formation of an ionic bond differs from the formation of a covalent bond by being so, a covalent bond forms when one electron in the outer electron orbit of each atom is shared between the two atoms. Covalent has only one electron to be shared and ionic has more than one electron to be transferred.

Polarity is measured on a scale of electronegativity (the electron d.pdf
Polarity is measured on a scale of electronegativity (the electron disparity between two elements
that are combined in a compound). The more electrons you take from your partner element in the
bonding process, the greater your negative charge, and the greater your electronegativity.
There are three terms to describe the polarity of a given molecular bond:
Ionic
Polar covalent
Non-polar covalent
Ionic is the most polar - essentially, one atom physically takes electrons from another atom,
creating a huge electron disparity between the two atoms. This tends to happen in molecules
where one atom has very few valence electrons and the other has a lot of valence electrons.
Sodium chloride (NaCl) is a good example of an ionic bond.
Polar covalent is the mid-range - technically closer to ionic. This happens when one atom
attempts to take electrons from its partner, but cannot quite attract them all to itself. The result is
a covalent bond between the two atoms where the valence electrons are \"shared,\" but the
sharing is unequal. One atom pulls the \"shared\" electrons a little closer to itself. Polar covalent
bonds usually occur between very electronegative elements; hydrogen paired with elements like
oxygen and fluorine almost always creates polar covalent bonds. A good example of a polar
covalent bond is found in water (H2O).
Non-polar covalent is the least polar - in fact, it is not polar at all. This occurs when valence
electrons are shared equally between two atoms. There is little or no tendency for either atom to
pull any of the electrons toward itself. Non-polar covalent bonds can often be seen in molecules
with two non-metals. Methane (CH4) is an example of a non-polar covalent bond.

In consumer behavior, the main entities that can influence the purchase decision of a consumer are: 1) innovators are the one who are basically risk takers. The main attribute of them are the fact that they are able to absorb the financial cost as well as the social cost of adopting the unsuccessful products. They are the one who extensively use commercial media, cosmopolitan in their outlook, uses professional source for getting information, etc. 2) Market mavens are the individuals who provide wide amount of information about the different kinds of products and services. They basically foster information related to product quality, features, availability, price and sales. Extroverted, conscientious, and extensive use of media are some of the main characteristics of market mavens. 3) Opinion leaders are the one who basically provides information about a particular product or activities. They are having more status than that of their followers and are socially active (Hawkins, Mothersbaugh and Best, 2012). In contrast to innovators, opinion leaders and market mavens that may affect consumer purchase decision are buying center that affects the organizations

Solution
After studying chapter 7 learning objectives, you should be able to:
Memory management is intended to satisfy the following requirements:
Relocation :
Programmers typically do not know in advance which other programs will be resident in main memory at the time of execution of their program.
Protection:
Processes need to acquire permission to reference memory locations for reading or writing purposes.
Sharing:
Advantageous to allow each process access to the same copy of the program rather than have their own separate copy.
Logical organization:
Physical organization:
Memory available for a program plus its data may be insufficient and overlying allows various modules to be assigned the same region of memory but is time consuming to program.

In certain chlorophyll cofactors the Mg2+ is axially coordinated by th.docx
In certain chlorophyll cofactors the Mg2+ is axially coordinated by the S-atom of a methionine. This is odd considering that Mg2+ is considered to be a “hard acid†cation. Why would water molecules be a more natural choice for coordination to the Mg2+ than sulfur? What is it then about this protein and its structure that makes the Mg-S coordination happen?
Solution
Mg 2+ is the bound central metal ion in chlorophyll which is the major photosynthetic pigment.In chlorophyll Mg 2+ is chelated equatorially by tetrapyrrolic macrocycle.One of the two axial position is occupied mainly by histidine residue and other by O-donors,N-donors or S atom.
According to Pearson classification Mg 2+belongs to hard ions and it\'s ionic radius is relatively small.It forms stable complexes with O- donors like H2O while less stable complexes with N donors or S atom.Since water is a polar molecule and is electron rich and also the distance between Mg 2+ and water is found to be 2.06 A° which is smaller compared to the others.
Also the water and Mg bond is electrostatic in nature.All this makes water and Mg 2+ coordination more stronger and preferred over S atom.
S is also being an electron rich ..it can also form bond with Mg 2+. These has been explained on the basis of Density functional theory which gives the distance between Mg 2+ and Water and S atom.

Topic pointers
Why do they call it dereferencing? As in dereferencing the pointer. Where does that name come from?
Solution
a.) A pointer is a variable that consists the address in memory of another variable. The deference of a pointer gives the contents of an object pointed to by the pointer.
b.) Through this we are accessing a variable indirectly. De- prefix mostly comes from the latin preposition meaning from. Dereferencing takes asway the reference and gives us what we are actually referring to.
c.) The unary operator * is the dereferecing operator ,which helps in accessing the object the pointer points to.
d.) Example:
typedef  struct X{int i_; double d_;} X;
XÂ Â Â x;
X*Â Â p= &x;
p->d_=3.15576;Â Â Â Â // dereferencing and accessing the data member x.d_

In C++ a function used to put data into a stack is typically called a.docx
In C++ a function used to put data into a stack is typically called a what?
Solution
Push function used to put data into a stack
A Stack is a data structure which works on the principle LIFO(Last In, First Out).The basic operations in a Stack are :
1. Push : In which we push the data into the stack.
2. Pop : In which we remove an element from the Stack.
All insertions and removals are done only from one side of the Stack , which is called the \'top\' of the Stack.
A stack is generally used in function calls where the local variables are pushed onto the Stack and when the function returns ,
it pops the variables from the Stack.
// Push operation to insert an element on top of stack.
void Push(int x)
{
if(top == MAX_SIZE -1) { // overflow case.
cout<<\"Error: stack overflow\ \";
return;
}
A[++top] = x;
}

In an alternative universe- all rules governing quantum numbers and th.docx
In an alternative universe, all rules governing quantum numbers and the periodic table are exactly the same as our universe EXCEPT that m l = 0 --> l + 2 (due to font issues: zero to the letter L plus 2)
Answer the following:
What changes are made to the appearance of the periodic table (how have the s, p, d and f blocks changed and what does that do to the table)?
What is the 2nd noble gas in the alternate universe?
Solution
Answer -
M l = 0 to l+2
for n=1 ; l= n-1 = 0;
M l =0 to l+2 = 0,1,2
Hence there is 3 subshell in s orbital which occupy 6 electron.
in the same way;
for n=2
l=2-1=1
M l = 0 to l+2 = 0,1,2,3
p-orbital occupy 8 electrons.
n=3
l=2
M l = 0 to l+2 = 0.1.2.3.4
d have 10 electron.
n=4
l=3
M l = 0 to l+2 = 0,1,2,3,4,5
f occupy 12 electron
Second noble gas = 6(1s) +6(2s) +8(2p) =20th element is second noble gas = which is calcium, Ca

In a Classical model of the macroeconomy- the equilibrating mechanism.docx
Solution
true
Keynesian economics (/?ke?nzi?n/ kayn -zee-?n ; or Keynesianism ) is the view that in the short run, especially during recessions, economic output is strongly influenced by aggregate demand (total spending in the economy). In the Keynesian view, aggregate demand does not necessarily equal theproductive capacity of the economy; instead, it is influenced by a host of factors and sometimes behaves erratically, affecting production, employment, and inflation. [1]
The theories forming the basis of Keynesian economics were first presented by the British economist John Maynard Keynes in his book, The General Theory of Employment, Interest and Money , published in 1936, during theGreat Depression. Keynes contrasted his approach to the aggregate supply-focused \'classical\' economics that preceded his book. The interpretations of Keynes that followed are contentious and several schools of economic thoughtclaim his legacy.
Keynesian economists often argue that private sector decisions sometimes lead to inefficient macroeconomic outcomes which require active policy responses by the public sector, in particular, monetary policy actions by thecentral bank and fiscal policy actions by the government, in order to stabilize output over the business cycle. [2] Keynesian economics advocates a mixed economy

In 2000- June- A 75-year-old widow- creates an irrevocable trust namin.docx
In 2000, June, A 75-year-old widow, creates an irrevocable trust naming her five adult grandchildren as the beneficiaries. The assets transferred in trust consist of marketable securities (worth $800,000) and June\'s personal residence (worth $400,000). Bob, June\'s younger brother and a practicing attorney, is designated as the trustee. Other provisions of the trust are as follows:
Bob is given the discretion to distribute the income to the beneficiaries based on their need or add it to corpus. He is also given the power to change trust investments and to terminate the trust.
The trust is to last for June\'s lifetime or, if sooner, until termination by Bob.
Upon termination of the trust, the principal and any accumulated income are to be distributed to the beneficiaries (June\'s grandchildren).
For 2000, June files a form 709 to report the transfer in trust and pays a gift tax based on value of $1.2 million ($800,000 + $400,000).
After the transfer in trust and up to the time of her death, June continues to occupy the residence. Although she pays no rent, she maintains the property and pays the yearly property taxes. June never discussed the matter of her continued occupancy of the residence with either Bob or the beneficiaries of the trust.
Upon June\'s death in 2008, the value of the trust is $2.3 million, broken down as follows: marketable securities and cash ($1.6 million) and residence ($700,000). Shortly thereafter, Bob sells the residence, liquidates the trust, and distributes the proceeds to the beneficiaries.
What are the estate taxes consequences of these transaction to June?
Solution
Since she pays her property taxes, there are no tax consequences on June.
However on selling the house, her children will have to pay tax on capital gains from the increase n the value of the house. To avoid this tax, they will have to live in the same house for two years.

Impulse and momentum are two two different parameters- Explain these p.docx
Impulse and momentum are two two different parameters. Explain these parameters from Newton\'s law of motion.
Solution
Impulse:impulse is dealing with the force.What it means is impulse is nothing but force that is applied on a object to against its motion for a given time.
J=Force* time
Momentum:which is a quantity deals with the object resistance to stop.Indirectly,object with greater momentum very hard to stop.
p=mv
consider the Newton\'s second law that is F=m*a
F=m*(v/t)
F*t=m*v
Here F*t nothing but impulse
m*v=momentum.
what it means is force that is acting on a given object for particular time changes the objects momentum.

Implementation of EHR
Discuss the advantages and disadvantages associated with implementing and using a regional and national EHR.
Solution
Advantages
Providing better, updated and accurate information about patient on regional and national level
It enables the quick access to patient record for better coordination and better care
It securely shares the electronic information of patients with clinics
Improve interaction and communication as well asa health care
Enables the safe and more reilable prescribtion
Disadvantages
Privacy is a concern when we record the data electronically, using the HER put organization at the risk if we don’t follow the privacy protocols
Identify theft can occur when unauthorized people gain advantage of access over the record.
Data loss and data redundancy are also the major disadvantages assocaited with HER softwares. When we use HER we must put into place a backup plan of the data Even if your local servers suffer a catastrophic crash, you will still be able to reconstruct your patient information through the backup in the cloud.

ii)State whether you would expect the following Group 13 metal cations.docx
ii)State whether you would expect the following Group 13 metal cations to act as Lewis acids or bases. Order the cations in terms of softest to hardest. Explain your answer. Al3+, Tl3+, Ga3+, Tl+
(iii) State whether you would expect the following Group 15 hydrides to act as Lewis acids or bases. Order the hydrides in terms of softest to hardest. Explain your answer. PH3, NH3, AsH3
Solution
ii) The given group 13 metal cations will act as a Lewis acids , because cations are are electron deficient and act as a electron acceptor.
Hard Acids are Lewis acid which are small in size and most likely are the light metal cation with high positive oxidation state like Al 3+
Soft Acids are Lewis acid which are larger in size and most likely are the heavy metal cation associated with low oxidation state like Tl 3+ Tl +
Oder of cation from softest to hardest   Tl + < Tl 3+ < Al 3+
(iii) The given Group 15 hydrides will acts as Lewis Base, because Nitrogen, Phosphorus and Arsenic has a lone pair of electron that it can donate.
Hard Base are Lewis base anions or neutral molecules which are not easily polarizable like NH 3
Soft Base are Lewis base anions or neutral molecules which are easily polarizable like PH 3 and AsH 3
Order the hydrides in terms of softest to hardest AsH 3 < PH 3 <NH 3

IMF in Greece- Good or bad for the country- Why-SolutionIMF is interna.docx
IMF in Greece. Good or bad for the country? Why?
Solution
IMF is international monetary fund.It was established with the motive of promoting international monetary cooperation.It is good because:
1. It helps in abolishing the exchange restrictions among member nations.
2. It helps in maintaining balanced economic development of the member nations by poviding them monetary help.
3. It helps the member countries in making investment in profitable projects.
4. It offers monetary help to member countries in correcting the disequilibrium of balance of payment.
IMF is bad because:
1. it is a club of rich countries only. it discriminate between rich and poor memebers.
2. it do not provides loan for developmental projects. it only gives loans for maintaining the favourable balance of payment.
3. it interferes in the domestic economies of member countries. while providing loan to member counties IMF put many restrictions.
4. IMF tried to maintain stability in price of gold but failed in achieving this aim.

2- What is a colloid- Why is it difficult to filter a colloid- 3- What.docx
2. What is a colloid? Why is it difficult to filter a colloid? 3. What is coagulation? What is peptization? 4. Why is the solution of AgNOs added slowly? 5. Why must a large excess of AgNOs be avoided? 6. Why must the silver chloride be protected from the light? 7. For simplicity assume that your unknown chloride is NaCl. Calculate how many mL of the 5% AgNO3 solution must be added to 0.4020 g of the NaCl sample to precipitate all the chloride. Note: 5% means that there are 5 grams of silver nitrate per 100 mL of solution.
Solution
2) Colloid : Colloid is a dispersion of small tiny particles in a liquid.. In collods the tiny particles remain suspended in the solvent. rather than settling at the bottom.
It is difficult to filter collodal solution because these tiny particles pass through the filter paper.
3) Coagulation : means the aggrigation of oppositely charged particles which settle down under the gravity.
Peptization : It is a phenomenon of the formation of a colloidal dispersion from precipitation.
4)Addition of the AgNO3 be done slowly because the addition tends to yield large particles which makes filtration more efficiently .It also helps limit coprecipitation.
5)To avoid coprecipatation the excess of AgNO3 be avoided.
6)Silver chloride must be protected from light as it is unstable. Exposure to light it becomes greyish yellow . Hence, to avoid decompostion, it must be protected from light.

2- The Mars Climate Orbiter (formerly the Mars Surveyor 98 Orbiter) wa.docx
2. The Mars Climate Orbiter (formerly the Mars Surveyor 98 Orbiter) was one of two spacecraft in the Mars Surveyor 98 program, the other being the Mars Polar Lander (formerly the Mars Surveyor 98 Lander). The two missions were to study the Martian weather, climate, and water and carbon dioxide badget in order to understand the reservoirs, behavior, and atmospheric role of volatiles and to warch for evidence of long-term and episodic climate changes. The Mars Climate Orbiter was destroyed when a navigation error caused the spacecraft to miss its intended 140-150 km altitude above Mars during orbit insertion, instead entering the Martian atmosphere at about 57 km. The spacecraft was destroyed by atmospherie stresses and friction at this low altitude. A review board found that some data was calculated on the ground in Imperial units (pound-seconds) and eported that way to the navigation team, who were expeeting the data in metric units (newton-seconds). Calculate the conversion between Newton-seconds and pound-seconds. (Hint: pound is the force of 1 slug being accelerated at 1 foot/see2, and 1 slug is 14.59 kg.) s. (Hint: 1 pound is the force of 1 slug being accelerated at 1 foot/see, and 1 slug
Solution
1 newtons = 0.224808942443 pounds
hence 1 newton -second = Â Â 0.224808942443 pounds -seconds

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

In a nonpolar covalent bond--- Electrons are shared unevenly Electrons.docx
- 1. In a nonpolar covalent bond... Electrons are shared unevenly Electrons are closest to the least electronegatative atom Electrons are hypervalent Electrons are donated from one atom to the other Electrons are shared evenly In a nonpolar covalent bond... Electrons are shared unevenly Electrons are closest to the least electronegatative atom Electrons are hypervalent Electrons are donated from one atom to the other Electrons are shared evenly Electrons are shared unevenly Electrons are closest to the least electronegatative atom Electrons are hypervalent Electrons are donated from one atom to the other Electrons are shared evenly Solution Ans . As a covalent bond is formed with the sharing of the electrons between atoms and not with the donation of electrons from one atom to another . Also , a polar covalent bond has uneven or unequal sharing of electrons due to difference in polarity while a non-polar covalent bond has even or equal sharing of electrons between atoms as there is no difference in polarity . Therefore , in a non-polar covalent bond electrons are shared evenly .
