Balancing Chemical Equations

Front

What is a Balanced Chemical Equation (BCE)?

Back

A Balanced Chemical Equation is an equation that shows the reactants and products of a chemical reaction with equal numbers of each type of atom on both sides, adhering to the Law of Conservation of Mass.

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that matter cannot be gained or lost in a chemical reaction; the total mass of reactants equals the total mass of products.

How do you determine if a chemical equation is balanced?

Back

A chemical equation is balanced if the number of atoms of each element is the same on both sides of the equation.

Front

What does it mean for a chemical equation to be unbalanced?

Back

An unbalanced chemical equation has unequal numbers of atoms of one or more elements on either side, violating the Law of Conservation of Mass.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical reaction, appearing on the left side of a chemical equation.

Front

What is a product in a chemical reaction?

Back

A product is a substance that is formed as a result of a chemical reaction, appearing on the right side of a chemical equation.
