Question

the law of conversation of mass is true for evey reaction​

Answer 1

Answer:

no

Explanation:

During a chemical reaction, atoms are neither created nor destroyed. The atoms of the reactants are just rearranged to form products. Hence, there is no change in mass in a chemical reaction.

Answer 2

Answer:

No

Explanation:

Mass is not conserved in chemical reactions. ... Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction. But mass+energy is always conserved. Energy cannot be created out of nothing.
