Law of Conservation of Mass

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction; it can only change forms.

Front

What happens to the total mass of substances after a chemical reaction?

Back

The total mass remains the same.

Front

What does it mean for a chemical reaction to be balanced?

Back

A chemical reaction is balanced when both sides have the same number of atoms of each element.

Front

Can matter be created or destroyed during a chemical reaction?

Back

No, matter cannot be created or destroyed; it can only be transformed.

Front

How does a balanced chemical equation relate to the Law of Conservation of Mass?

Back

A balanced chemical equation shows that the total amount of matter stays the same during a chemical reaction.

Front

What is an example of a chemical reaction that demonstrates the Law of Conservation of Mass?

Back

The reaction of hydrogen and oxygen to form water, where the total mass of reactants equals the total mass of products.

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of molecules or moles of each substance involved in the reaction.

Front

What is the difference between reactants and products in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change, while products are the substances formed as a result of the reaction.

Front

What does it mean to transform matter?

Back

To transform matter means to change its form or state, such as from solid to liquid, without changing its total mass.

Front

What is an example of matter being transformed?

Back

Melting ice into water is an example of matter being transformed.
