Answer 1

A. The total amount of matter cannot be created or destroyed.

Matter can be transformed but never created or destroyed.

Answer 2

A The total amount of matter cannot be created

or destroyed.

Explanation:The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
