Remember that you are telling someone how the reaction was done and what the. Substances on the left hand side of the arrow are called reactants (starting material). Substances on the right hand side of the arrow are called products (the results). (aq) mean a aqueous or water solution (g) means a gaseous form (s) means a solid form (l) means a pure liquid form. Diatomic molecules several elements occur naturally as molecules with two atoms or as diatomic molecules and are part of chemical reactions. These are br, i, n, cl, h, o, f or brinclhof. 7. 3 steps for balancing an equation: check to see that the formulas of all reactants and products are correct. Formulas are never changed to balance an equation. Nacl is always nacl and never na2cl2: balance each element in the equation by placing a coefficient in front of each substance.
