How can you tell the mass was conserved in a chemical reaction?

KengaRu [80]

Answer:

$\boxed {\boxed {\sf Mass \ of \ products \ = \ mass \ of \ reactants}}$

Explanation:

The Law of Conservation of Mass states that mass cannot be created or destroyed.

In a chemical reaction, there are products and reactants. The reactants <em>react</em> and <em>produce</em> the products.

Since mass can't be created or destroyed, the mass of the products must be equal to the mass of the reactants if mass was conserved in a chemical reactions.
