A chemical reaction is a process in which one set of chemical substances (reactants) is converted into another (products). It involves making and breaking chemical bonds and the rearrangement of atoms.
Chemical changes occur when a substance combines with another substance to form a new substance. These are called chemical reactions and they are irreversible or very hard to â¦reverse. When a chemical reaction takes place, the atoms are rearranged and the reaction is accompanied by an energy change when the new products are formed.
