Question

The mass before a reaction is equal to the mass after a reaction? True or false?

Answer 1

Answer:

$\boxed {\boxed {\sf True}}$

Explanation:

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

So, in a chemical reaction, the mass before a reaction and after cannot be different. In other words, the mass of the products must be equal to the product of the reactants.

So, this is a true statement.
