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, ensuring the law of conservation of mass is followed.

What does the coefficient in a chemical equation represent?

Back

The coefficient in a chemical equation represents the number of moles of a substance involved in the reaction. It indicates how many molecules or formula units participate in the reaction.

How do you determine the correct coefficients for balancing a chemical equation?

Back

To determine the correct coefficients, start by counting the number of atoms of each element in the reactants and products. Adjust the coefficients to ensure that the number of atoms for each element is equal on both sides.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. Therefore, the total mass of reactants must equal the total mass of products.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes a change during a chemical reaction. It is present at the start of the reaction.

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. It is present at the end of the reaction.
