* 1) C + O2 = CO2
2) CO2 + H2O = H2CO3
3) H2CO3 = CO2 + H2O
4) CO2 + 2NaOH = Na2CO3 + H2O
5)C+O2=CO2
6)CO2+H2O=H2CO3
7)H2CO3+CaO=CaCO3+H2O
8)CaCO3=CaO+CO2
*
1)CuO+H2-->Cu+H2O
2)2Cu+O2-->2CuO
3)CuO+2HNO3-->Cu(NO3)2+ H2O
4) Cu(NO3)2+2NaOH-->Cu(OH)2+2NaNO3
5)Cu(OH)2-->CuO+H2O
6)CuO+H2-->Cu+H2O
2Cu + O2 = 2CuO
CuO + 2HCl = CuCl2 + H2O
3CuCl2 + 2Al(OH)3 = 3Cu(OH)2 + 2AlCl3
Cu(OH)2 = CuO + H2O (над равно напиши t)
CuO + H2SO4 = CuSO4 + H2О
