Balancing Chemical Equations

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, ensuring the law of conservation of mass is followed.

Front

What is the first step in balancing a chemical equation?

Back

Identify the number of atoms of each element on both sides of the equation.

What does it mean if a chemical equation is already balanced?

Back

It means that the number of atoms for each element is the same on both sides of the equation, and no coefficients need to be added.
