Chapter 14, Problem 14.128P

(a)

Interpretation Introduction

Interpretation:

The chemical equations for given reactions have to be written.

Concept Introduction:

Balanced Chemical equation:

A balanced chemical equation is an equation which contains same elements in same number on both the sides (reactant and product side) of the chemical equation thereby obeying the law of conservation of mass.

(b)

Interpretation Introduction

Interpretation:

The chemical reaction for production of ${\text{PH}}_{\text{3}}$ from ${\text{Ca}}_{\text{3}}{\text{P}}_{\text{2}}$ and water has to be written.
