Answer:
The correct answer is: 'Nitrogen is relatively inert'.
Explanation:
As, atomic number of nitrogen is 7 and its electronic distribution is 2, 5. Hence, there are 5 valence electrons present in a nitrogen atom. And, to attain stability it will gain three electrons from a donor atom. Hence, it will make a triple bond.
Therefore, nitrogen has 5 valence electrons and makes 3 bonds in neutral compounds.Thus nitrogen will combine with another nitrogen atom to completes its octet to form gas molecule. Due to the presence of this triple bond, the gas molecule is almost inert as its bond dissociation energy is very high.
<u>Hence, the correct option is:- nitrogen is relatively inert.</u>
Answer:
Blue vitriol is crystal copper sulphate
Explanation:
The black oxide is the higher oxide of Copper i.e Cu. It is also called as tenorite. It is solid black in color. It is formed by heating copper with air.
Blue vitriol is the crystalline form of copper sulphate. It is also known as copper (II) sulphate.
When heating, the blue vitriol undergoes various steps of changes to the black oxide of copper.
The chemical reaction is --
