Law of Conservation of Mass

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that in a closed system, mass is neither created nor destroyed during a chemical reaction. The total mass of reactants equals the total mass of products.

Front

What are reactants in a chemical equation?

Back

Reactants are the substances that undergo a chemical change in a reaction. They are found on the left side of a chemical equation.

Front

What are products in a chemical equation?

Back

Products are the substances that are formed as a result of a chemical reaction. They are found on the right side of a chemical equation.

Front

What does the arrow in a chemical equation represent?

Back

The arrow in a chemical equation indicates the direction of the reaction, pointing from reactants to products.

Front

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

Back

The total number of atoms is 45, calculated by adding 12 (C) + 22 (H) + 11 (O).

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides, ensuring mass is conserved.

Front

What is the significance of the coefficients in a chemical equation?

Back

Coefficients indicate the number of molecules or moles of each reactant and product involved in the reaction.

Front

What happens to mass during a chemical reaction?

Back

The total mass remains constant; it is conserved throughout the reaction.

Front

Can a chemical reaction create or destroy atoms?

Back

No, a chemical reaction cannot create or destroy atoms; it only rearranges them.
