(a)
Interpretation:
The reversible reaction for the reaction of chlorine gas to form liquid chlorine needs to be determined.
Concept introduction:
The
Explanation of Solution
When a double arrow is placed between reactant and product, the chemical equation is represented as follows:
According to above chemical equation, A and B react to form AB and AB can further dissociate to form A and B. Thus, the reaction is reversible in nature.
The reaction showing chlorine gas to form liquid chlorine is represented as follows:
Here, 1 mol of chlorine gas gets converted into 1 mol of liquid chlorine.
(b)
Interpretation:
The reversible reaction for the reaction of nitrogen dioxide to form dinitrogen tetraoxide needs to be written.
Concept introduction:
The chemical reaction is represented in the form of an equation in which reactants are written on the left hand side and products on right hand side. The reactants and products are separated by placing an arrow between them.
Explanation of Solution
The reaction showing nitrogen dioxide to form dinitrogen tetraoxide is represented as follows:
Here 2 moles of nitrogen dioxide form 1 dinitrogen tetraoxide.
(c)
Interpretation:
The reversible reaction for the precipitation of silver chloride from aqueous solution needs to be determined.
Concept introduction:
The chemical reaction is represented in the form of an equation in which reactants are written on the left hand side and products on right hand side. The reactants and products are separated by placing an arrow between them.
(c)
Explanation of Solution
The silver chloride is formed when silver nitrate solution which is colorless is added to colorless aqueous solution of sodium chloride, silver chloride is formed which is a white precipitate.
The reaction showing precipitation of silver chloride is represented as follows:
(d)
Interpretation:
The reversible reaction for evaporation of water needs to be written.
Concept introduction:
The chemical reaction is represented in the form of an equation in which reactants are written on the left hand side and products on right hand side. The reactants and products are separated by placing an arrow between them.
(d)
Explanation of Solution
Liquid water can evaporate to form steam or water vapor. The reaction showing evaporation of water is as follows:
Here, only state of water changes from liquid to gas.
