Chapter 7, Problem 84E

Interpretation Introduction

(a)

Interpretation:

The reaction ${\text{PCl}}_5\left(s\right)+{\text{H}}_{\text{2}}\text{O}\left(l\right)\to {\text{H}}_3{\text{PO}}_{\text{4}}\left(aq\right)+\text{HCl}\left(aq\right)$ is to be balanced.

Concept introduction:

A balanced chemical equation represents an equation in which all the reactants and products are written with their stoichiometric coefficient and physical states. The number of atoms of an element on the both sides of the equation is equal.

Interpretation Introduction

(b)

Interpretation:

The reaction ${\text{TiCl}}_4\left(s\right)+{\text{H}}_{\text{2}}\text{O}\left(l\right)\to {\text{TiO}}_{\text{2}}\left(s\right)+\text{HCl}\left(g\right)$ is to be balanced.

Concept introduction:

A balanced chemical equation represents an equation in which all the reactants and products are written with their stoichiometric coefficient and physical states. The number of atoms of an element on the both sides of the equation is equal.
