Ответ:
1.2Cu + O2 = 2CuO
CuO + H2SO4 = CuSO4 + H2O
CuSO4 + 2NaOH = Na2SO4 + Cu(OH)2
Cu(OH)2 + 2HCl = CuCl2 + 2H2O
Cucl2=cu+cl2
2.2Zn+O2=2ZnO
ZnO+H2SO4=ZnSO4+H2O
ZnSO4+2KOH=Zn(OH)2+K2SO4
Zn(OH)2+2NaOH=Na2ZnO2+2H2O
3.4P+5O2=2P2O5
P2O5+3H2O=2H3PO4
H3PO4+3NAOH=NA3PO4+3H2O
2NA3PO4+3CACL=3NACL+CA2(PO4)2
4.2Mg + O2 = 2MgO
MgO + H2O = Mg(OH)2↓
Mg(OH)2 + 2HCI = MgCI2 + 2H2O
MgCl2+2AgNO3=Mg(NO3)2+2AgCl
