Chapter 12.1, Problem 8LC

Interpretation Introduction

Interpretation: To determine quantities that are always conserved in a chemical reaction.

Concept Introduction: In a chemical reaction, one or more reactants are converted into one or more additional substances also known as products.

Answer to Problem 8LC

The total mass as well as the atom will be always conserved during the chemical reaction.

Explanation of Solution

Chemical reactions can neither generate nor destroy matter. This refers to the principle of mass conservation. The amount of matter that began in the reactants should equal the amount of matter that is produced in every chemical reaction. Mass would be preserved in chemical reactions, as demonstrated by balanced chemical equations.

Therefore, mass, as well as an atom of the reaction, will be always conserved.
