Step-by-step explanation:
A chemical reaction is defined as the process in which one or more substances reacts to form one or more products which are chemically transformed means the constituent atoms of the reactants are rearranged unlike physical reactions. No new atoms are created or destroyed, bonds between the atoms in the reactants are broken and the atoms rearrange themselves and form new bonds to make the product. For example iron and oxygen combine to form rust, sodium acetate is formed by the combination of vinegar and baking soda etc.
