what is chemical reaction
A chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds. chemical reaction is a process that is usually characterized by a chemical change in which the starting materials (reactants) are different from the products.
