What type of bond would be formed between nitrogen (N) and nitrogen (N)? Why?
Vikki [24]

Answer: The compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Explanation:

If electronegativity difference between two atoms is less than 0.4 then bond formed is a pure covalent bond.

If electronegativity difference between two atoms is between 0.4 to 1.8 then bond formed is a polar covalent bond.

If electronegativity difference between two atoms is greater than 1.8 then bond formed is an ionic bond.

The electronegativity value of a nitrogen atom is 3.04. Hence, the electronegativity difference of N_{2} molecule is as follows.

Electronegativity difference = electronegativity value of N - electronegativity value of N\\= 3.04 - 3.04\\= 0As the electronegativity difference is 0 which is less than 0.4.

Hence, we can conclude that the compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

In alpha and beta decay the parent element and the daughter element can be
Angelina_Jolie [31]
In alpha and beta decay the parent element and the daughter element will be different isotope and not the same. 
This is because as alpha particles comes out; the new element will have two less in atomic number; that is the atomic number will reduce by two and the mass number will reduce by four. While in a beta particle decay, the new element will have one higher in atomic number; that is the atomic number will increase by one.

<span>the balanced equation for the reaction is as follows
2C</span>₄H₁₀ + 13O₂ ---> 8 CO₂ + 10H₂<span>O
 stoichiometry of C</span>₄H₁₀ to O₂ <span>is 2:13
stoichiometry applies to the molar ratio of reactants and products. Avagadros law states that volume of gas is directly proportional to number of moles of gas when pressure and temperature are constant.
 Therefore volume ratio of reactants is equal to molar ratio, volume ratio of C</span>₄H₁₀ to O₂<span> is 2:13
 2 L of </span>C₄H₁₀ reacts with 13 L of O₂<span> 
then 100 L of </span>C₄H₁₀<span> reacts with 13/2 x 100 = 650 L
 therefore 650 L of O</span>₂<span> are required </span>
