Chapter 5, Problem 167MP

(a)

Interpretation Introduction

Interpretation:Formula of product ${\text{A}}_x{\text{B}}_y$ is to be specified.

Concept introduction:The reactant in a reaction that tells about amount of product formed in a reaction is termed as limiting reagent. It helps to determine the yield of reaction.

The quantity of species that gives relation between reactants and products is determined by the stoichiometry of a reaction. Suppose the general reaction,

  $\text{2A}+\text{B}\to 3\text{C}$

In the above reaction, two moles of $\text{A}$ reacts with one mole of $\text{B}$ to form three moles of $\text{C}$ . Therefore, stoichiometric ratio of A and B is $2:2$ , of A and C is $2:3$ and of B and C is $1:3$ .

(b)

Interpretation Introduction

Interpretation:Molecular formula and empirical formula is to be determined.

Concept introduction: Formula that provides ratio of atoms present in compound in its simplest form is termed as empirical formula.
