Chapter 18, Problem 16E

Interpretation Introduction

Interpretation: The balanced equations of $\text{Sr}$ with ${\text{O}}_2,{\text{ S}}_{\text{8}},{\text{ Cl}}_{\text{2}},{\text{ P}}_{\text{4}},{\text{ H}}_{\text{2}},{\text{ H}}_{\text{2}}\text{O}$ , and $\text{HCl}$ needs to be determined.

Concept introduction: Chemical equation is written in such a way that the symbolic representation of reaction represents the reaction taking place in the system. The reactants are written on the left-hand side and the products are written on the right-hand side of the equation and are separated by an arrow, two or more reactants and products are separated by “+”.

The reactions for those the number of atoms of each element in the reactant and in the product, side are equal, such reactions are said to be a balanced chemical equation.
