What is the number of pairs of electrons that are shared between the nitrogen atoms in a molecule of N2?(1) 1(2) 2(3) 3(4) 6

Answers

Answer 1
Answer: The answer is (3) 3. The sharing of electrons is important to help elements get 8 electrons in the outer shell to be stable. To achieve this aim, the nitrogen needs to share three pairs of electrons.
Answer 2
Answer:

The number of pairs of electrons that are shared between nitrogen atoms in a molecule of {{\text{N}}_{\text{2}}} is \boxed{\left( 3 \right){\text{ 3}}}.

Further explanation:

Covalent Bond

It is a type of chemical bond where electrons are mutually shared between the bonded atoms. This bond is also known as a molecular bond. The compounds formed as a result of this bonding are covalent compounds.

Octet Rule

It is a thumb rule that describes the tendency of elements to bond with other elements in order to acquire eight valence electrons. As a result, elements tend to achieve stable noble gas configuration.

The atomic number of nitrogen is 7 and it has an electronic configuration of 1{s^2}2{s^2}2{p^3}. Nitrogen has five valence electrons in it and is three electrons short of the stable noble gas configuration of neon. So it can share three electrons with another nitrogen atom to complete its octet. As a result, three covalent bonds are formed between two nitrogen atoms. In other words, nitrogen atoms have a triple bond between them in   molecule (For structure, refer to the attached image).

What Is Oxidation Reaction

Answers

Oxidation reaction is a type of reaction wherein there is  a loss of electrons. An oxidation reaction may also be a reducing agent. Example is the reaction Zn + 2H+ = Zn2+ + H2. When you separate them by their half cell reaction, you have 2H+ 1e- = H2. H here is the reducing agent and has lost 1 electron in the process.

Compounds that do not conduct an electric current in either aqueous solution or when molten are referred to as _____.a. electrolyte
b. nonelectrolyte
c. not listed
d. ionic

Answers

The answer is B. Nonelectrolyte. Nonelectrolytes are substances that do not dissociate into ions when dissolved in a solution. In some cases, they dissociate into molecules rather than ions. They are usually polar covalent substances such as sucrose (C12H22O11). Nonelectrolytes are considered to be poor conductors of electricity.

A gas has experienced a small increase in volume but has maintained the same pressure and number of moles. According to the ideal gas law, how has the temperature of the gas changed?

Answers

temperature has increased

Ideal Gas Law:

pressure * volume = (number of moles of gas) * (0.08206) * (temperature)

or short-hand:
PV = nRT

this equation can be transformed to solve for temperature as:
T = PV / nR

given there is no change in pressure and the volume of the container has increased, we know the temperature increases because volume is in the numerator--a larger number on top reflects an overall greater number.

B) It has increased slightly
