State balanced chemical equations for the reactions of the subsequent three metals with sulfuric acid, H2SO4. Underneath each reaction, State in order, (i) the group number of the metal element in the periodic table, (ii) the oxidation number of the metal in the sulfate salt produced as a reaction product and (iii) the volume (mL) of hydrogen gas, at standard conditions, that will be liberated by the reaction of sulfuric acid with the metal.
