Law of Mass Conservation Quiz

What is the Law of Conservation of Mass?

• Mass can be created or destroyed in a closed system.

• In a closed system, mass cannot be created or destroyed, only changed or transferred.

• Mass can only be transferred in a closed system.

• The Law of Conservation of Mass applies only to open systems.

Who proposed the Law of Conservation of Mass?

• Isaac Newton

• Albert Einstein

• Marie Curie

• Antoine Lavoisier

State the Law of Conservation of Mass.

• Mass can change form in a chemical reaction.

• Mass cannot be created or destroyed in a chemical reaction.

• Mass can be destroyed in a chemical reaction.

• Mass can be created in a chemical reaction.

What does the Law of Conservation of Mass state about chemical reactions?

• The total mass of the reactants is greater than the total mass of the products.

• The Law of Conservation of Mass does not apply to chemical reactions.

• The total mass of the reactants is less than the total mass of the products.

• The total mass of the reactants is equal to the total mass of the products.

What is the formula for the Law of Conservation of Mass?

• Mass can be created but not destroyed.

• Mass can be both created and destroyed.

• Mass cannot be created or destroyed

• Mass can be destroyed but not created.

What is the Law of Multiple Proportion?

• The Law of Multiple Proportion states that the ratio of the masses of elements in a compound can be expressed in irrational numbers.

• The Law of Multiple Proportion states that the ratio of the masses of elements in a compound can be expressed in small whole numbers.

• The Law of Multiple Proportion states that the ratio of the masses of elements in a compound can be expressed in fractions.
