(b)
Interpretation:
The theoretical yield of
Concept introduction: Theoretical yield is the maximum amount of product that can be obtained from a chemical reaction such that one of the reactants is completely consumed called limiting reagent. The maximum amount of product formed can be predicted from the stoichiometric coefficient of the limiting reagent in the balanced chemical reaction.
(c)
Interpretation:

The expression for
(d)
Interpretation:
The solubility of
Concept introduction: The solubility of insoluble salts containing anions (conjugate base of a weak acid) such as hydroxide, acetate, carbonate, phosphate and sulfide increases in the presence of strong acid than in pure water. Whereas the solubility of insoluble salts containing anions (conjugate base of a strong acid) such as chlorides decreases in the presence of strong acid than in the pure water.
