Chapter 9.1, Problem 6PP

Interpretation Introduction

Interpretation:

The chemical equation for the reaction of zinc with hydrogen sulphate to produces a gas and a solution of zinc sulphate needs to be determined.

Concept introduction:

The chemical equation is the way of writing chemical reaction with the help of chemical formulas of the reactants and products. To write the chemical equation, one must know the chemical formulas of products and reactants. The chemical equation is a balanced chemical equation.

Answer to Problem 6PP

The chemical equation is as follows:

$\text{Zn (}s{\text{)+H}}_2{\text{SO}}_{\text{4}}(aq)\to {\text{ZnSO}}_{\text{4}}(aq)+{\text{H}}_{\text{2}}(g)$

Explanation of Solution

The reaction of a metal and acid produces hydrogen gas. In the given reaction, zinc is metal and hydrogen sulpahte (sulphuric acid) is acid and they react to form hydrogen gas and zinc sulpahte. So, the name of the gas is hydrogen. The chemical equation is as follows:

$\text{Zn (}s{\text{)+H}}_2{\text{SO}}_{\text{4}}(aq)\to {\text{ZnSO}}_{\text{4}}(aq)+{\text{H}}_{\text{2}}(g)$

The above equation is balanced chemical equation.

Conclusion

When a metal reacts with acid hydrogen gas is produced.
