Question

what are the purposes of a chemical equation? check all that apply.

□ to show how substances in a chemical reaction interact
□ to shorten the explanation of a chemical reaction
□ to make chemical reactions easier to recognize
□ to help keep track of atoms in a chemical reaction
□ to show just the products of a chemical reaction

Explanation:

A chemical equation shows how substances in a reaction interact (reactants and products). It helps keep track of atoms (due to the law of conservation of mass). It makes chemical reactions easier to recognize (standardized format). While it shows products, its main purpose is broader than just showing products. And it doesn't shorten the explanation; rather, it represents the reaction in a standard way.

Answer:

to help keep track of atoms in a chemical reaction, to make chemical reactions easier to recognize, to show how substances in a chemical reaction interact
