        MgCI2      MgSO4  Осуществите превращение)))

Answer 1

1) 2Mg + SiO2 = 2MgO + Si

2) MgO + 2H2O = Mg(OH)2 + H2

3) MgO + 2HCl = MgCl2 + H2O

4) Mg(OH)2 + H2SO4 = MgSO4 + 2H2O

Answer 2

2Mg + SiO2=Si + 2 MgO
MgO + H2O = Mg(OH)2............. и.......... MgO+ 2HCl= MgCl2 + H2O
 Mg(OH)2 + Na2SO4= 2NaOH+ MgSO4
