Chemical Equations Chemical equations: Describe proportions of reactants (the substances that are consumed) and products (the substances that are formed) during a chemical reaction. Describe the changes on the atomic level. » SO 3 ( g ) + H 2 O( l ) → H 2 SO 4 ( l ) » Fe 2 O 3 ( s ) + 3H 2 SO 4 ( aq ) → 3H 2 O( l ) + Fe 2 (SO 4 ) 3 ( aq ) Physical state of products/reactants: » ( s ) = solid; ( l ) = liquid; ( g ) = gas; ( aq ) = aqueous soln.
