Mg-MgO-MgCl2-Mg(OH)2-MgSO4-Mg3(PO4)2

Question

Mg-MgO-MgCl2-Mg(OH)2-MgSO4-Mg3(PO4)2

Answer 1

2Mg+O2=2MgO

MgO+2HCl=MgCl2+H2O

MgCl2+2NaOH=Mg(OH)2+2NaCl

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

3MgSO4+2H3PO4=Mg3(PO4)2+3H2SO4

Answer 2

1)2Mg + O2 = 2MgO

2)MgO + 2HCl = MgCl2 + H2O

3)MgCl2 + 2NaOH = Mg(OH)2(осадок) + 2NaCl

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

5)3MgSO4 + 2K3PO4 = Mg3(PO4)2(осадок) + 3K2SO4
