Помогите решить, срочно...

Alexei78 1)
MgCO3 = MgO + CO2↑
MgO + 2HNO3 = Mg(NO3)2 + H2O
Mg(NO3)2 + 2KOH = Mg(OH)2↓ + 2KNO3
Mg(OH)2 = MgO + H2O
2)
CuSO4 + 2NaOH = Cu(OH)2↓+Na2SO4
Cu((OH)2 = CuO + H2O
CuO + H2 = Cu + H2O
2Cu + O2 = 2CuO
3)
BaCO3 + H2SO4 = BaSO4 + H2O + CO2↑
CO2+ 2KOH = K2CO3 + H2O
H2O + K2O = 2KOH
KOH + HCl = KCl + H2O
4)
Fe(OH)2 = FeO + H2O
FeO + 2HCl = FeCl2 + H2O
FeCl2 + 2NaOH = Fe(OH)2↓+2NaCl
Fe(OH)2 + 2HNO3 = Fe(NO3)2 + 2H2O

MgCO3-->MgO+CO2
MgO+2HNO3-->Mg(NO3)2+2H2O
Mg(NO3)2+2NaOH-->Mg(OH)2+2NaNO3
Mg(OH)2-->MgO+H2O

СuSO4+2NaOH-->Cu(OH)2+Na2SO4
Cu(OH)2-->CuO+H2O
CuO+C-->Cu+CO
2Cu+O2-->2CuO

BaCO3+H2SO4-->BaSO4+H2O+CO2
CO2+2KOH-->K2CO3+H2O
2H2O+K-->KOH+H2
KOH+HCL-->KCL+H2O

Fe(OH)2-->FeO+H2O
FeO+2HCL-->FeCL2+H2O
FeCL2+2KOH-->Fe(OH)2+2KCL
Fe(OH)2+2HNO3-->Fe(NO3)2+2H2O
