Question

(b) How can you show that there is no change
in total mass during a chemical reactions.... help me​

Answer 1

Answer:

Do the same for the products. For each reaction compare the mass of the reactants to the mass of the products. ... Mass does not appear or disappear in chemical reactions. Mass is conserved, in other words, the total mass you start with is the total mass you will end with.

Explanation:

Answer 2

Answer:

first of all you need to understand this

Explanation:

Law of conservation of mass

The law of conservation of mass states that the total mass of substances taking part in a chemical reaction is conserved during the reaction.

Do the same for the products. For each reaction compare the mass of the reactants to the mass of the products. ... Mass does not appear or disappear in chemical reactions. Mass is conserved, in other words, the total mass you start with is the total mass you will end with.

Mass is never lost or gained in chemical reactions. We say that mass is always conserved. In other words, the total mass of products at the end of the reaction is equal to the total mass of the reactants at the beginning. This is because no atoms are created or destroyed during chemical reactions.
