Calcium Chloride and Sodium Bicarbonate

• The atoms in the reactants are: 1 calcium atom, 2 chlorine atoms, 2 sodium atoms, 2 hydrogen atoms, 2 carbon atoms, and 6 oxygen atoms
• The atoms in the products are: 1 calcium atom, 2 chlorine atoms, 2 sodium atoms, 2 hydrogen atoms, 2 carbon atoms, and 6 oxygen atoms
• The chemical equation is balanced because the same type and number of atoms are in the reactants and products.
