hey mate !! ♥️

Ur answer ।।।।

In a chemical change, the molecules in the reactants interact to form new substances. ... When an equation of a chemical reaction is written, it is “balanced” and shows that the atoms in the reactants end up in the products and that no new atoms are created and no atoms are destroyed.
