What goes in, must come out. So the elements on the right hand side, are also on the left hand side. Just bonded differently

There is the same overall number of atoms of each element on the reactants side as on the products side, they are simply rearranged. Also, mass is conserved as atoms cannot be created or destroyed by a chemical reaction.
