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. The total mass of reactants equals the total mass of products.

What is a reactant in a chemical reaction?

Back

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

Front

How do you determine if a chemical equation is balanced?

Back

Count the number of atoms of each element on both sides of the equation. If they are equal, the equation is balanced.

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of molecules or moles of a substance involved in the reaction, helping to balance the equation.

What is the total mass of products if 24 g of magnesium reacts with 38 g of fluorine?

Back

The total mass of products is 62 g, which is the sum of the masses of the reactants.

Front

What happens to the mass of reactants during a chemical reaction?

Back

The mass of reactants remains constant and is equal to the mass of the products after the reaction.
