Answer 1

Answer:

law of conservation of mass

Explanation:

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations.

According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.

Terms

reactantAny of the participants present at the start of a chemical reaction. Also, a molecule before it undergoes a chemical change.

law of conservation of massA law that states that mass cannot be created or destroyed; it is merely rearranged.

productA chemical substance formed as a result of a chemical reaction.
