Make up the equations of the substitution reactions: 1. … + sulfuric acid → magnesium sulfate + … 2. … + water → lithium hydroxide + … 3.iron + … → iron (II) sulfate + copper 4 .zinc + mercury (II) nitrate → …. + … 5.aluminum + … → aluminum chloride + hydrogen 6.barium + … → barium hydroxide + hydrogen

1) Mg + H2SO4 = MgSO4 + H2 – magnesium replaces hydrogen in acid, forming a salt of magnesium sulfate and hydrogen.
2) Li + 2H2O = 2LiOH + H2 – lithium replaces hydrogen, forming lithium hydroxide and hydrogen.
3) Fe + H2SO4 = FeSO4 + H2 – iron replaces hydrogen, forming iron sulfate and hydrogen.
4) 2Zn + Hg (NO3) 2 = 2ZnNO3 + Hg – zinc replaces mercury, forming zinc nitrate and metallic mercury.
5) Al + 6HCl = 2AlCl3 + 3H2 – aluminum replaces hydrogen, forming aluminum chloride and hydrogen.
6) Ba + 2H2O = Ba (OH) 2 + H2 – barium replaces hydrogen in the compound, thus forming barium hydroxide and hydrogen.
