+2HCl + Zn => ZnCl2 + H2, we will see the bubble of H2 in the solution
+Ca + 2H2O => Ca(OH)2 + H2
Ca(OH)2 + 2HCl => CaCl2 + 2H2O
or Ca + 2HCl => CaCl2 + H2, we will see bubble of H2
+H2SO4 + Zn => ZnSO4 + H2
+H2SO4 + Ca => CaSO4 + H2, we will see the bubble of H2, and white precipitate of CaSO4
+H2SO4 + Mg => MgSO4 + H2
