Question

Помогите решить:
Li2O+...=LiNO3+H2O
CuO+...=CuCl2+H2O
Li2O+....=LiOH
P2O5+...=H3PO4
SO3+...=Na2SO4+...
И второе:
Сu=CuO=CuCl2=Cu

Answer 1

Li2O + 2HNO3 = 2LiNO3 + H2O
CuO + 2HCl = CuCl2 + H2O
Li2O + H2O = 2LiOH
P2O5 + 3H2O = 2H3PO4
SO3 + 2NaOH = Na2SO4 + H2O

2Cu + O2 = 2CuO
CuO + 2HCl = CuCl2 + H2O
CuCl2 + 2Na = Cu + 2NaCl
