At the end of chemical reactions, what is the total mass of the reactants compared to the total mass of the products?
zhuklara [117]
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.
