Physical Science: Balancing Equations

Front

Is the chemical equation balanced?

Back

Yes, a balanced chemical equation has the same number of each type of atom on both sides of the equation.

Front

What law states that the total mass remains the same in a chemical reaction?

Back

Law of Conservation of Mass: This law states that mass is neither created nor destroyed in a chemical reaction.

Front

How many carbon atoms are in C6H12O6?

Back

Front

What is the relationship between the total mass of reactants and products in a sealed reaction?

Back

The mass is the same; it does not change.

Front

What are the numbers in front of compounds in a chemical equation called?

Back

Coefficients: These are used to balance the equation.

Front

What is a chemical equation?

Back

A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products.

Front

What does it mean to balance a chemical equation?

Back

Balancing a chemical equation means adjusting the coefficients to ensure the same number of each type of atom appears on both sides.

Front

What is a reactant in a chemical reaction?

Back

A reactant is a substance that undergoes change during a chemical 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.

Front

What is the significance of the Law of Definite Proportions?

Back

This law states that a chemical compound always contains its component elements in fixed ratio by mass.
