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; it remains constant.

Front

What does an exothermic reaction do?

Back

An exothermic reaction releases energy, usually in the form of heat, to its surroundings.

Front

What does an endothermic reaction do?

Back

An endothermic reaction absorbs energy from its surroundings, usually in the form of heat.

Front

Can a chemical reaction have more than one product?

Back

Yes, a chemical reaction can produce multiple products.

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 difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance but not its chemical composition, while a chemical change results in the formation of new substances.

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, reflecting the Law of Conservation of Mass.

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 a reaction.

Front

What is the role of energy in chemical reactions?

Back

Energy is required to break bonds in reactants and is released when new bonds form in products.
