b) Mg + 2HCl → H2 + MgCl2
if the H2 doesn't react with the O2 in the air forming water vapor.

Mg(s) + 2H(aq) = Mg(aq) + H2(g) is the superb equation and to get 2Mg + 4HCL = 2MgCL2 + 2H2 , all u have carried out is multiply( Mg(s) + 2H(aq) = Mg(aq) + H2(g) ) X 2 so why write the doubled once you have the numerous undemanding one
