Chapter 12, Problem 71A

Interpretation Introduction

Interpretation : The law of conservation of mass holds in a net ionic equation is to be explained.

Concept Introduction : Reactants, products, and an arrow indicating the reaction's direction make up a chemical equation. For a low-energy thermodynamic process, the reactant and product masses must match up in accordance with the law of conservation of mass.

Answer to Problem 71A

Yes, the law of conservation of mass holds in a net ionic equation because charges or electrons are preserved in a chemical equation.

Explanation of Solution

The chemical equation known as the net ionic equation only displays the substances that are directly involved in the chemical process.

Because charge (electron) must also be preserved in a net ionic equation in addition to the number of atoms of each type, the law of conservation of mass will continue to apply.
