NiggaStyle А)
CaCO3 = CaO + CO2
CaO + H2O = Ca(OH)2
Ca(OH)2 + 2HCl = CaCl2 + 2H2O
CaCl2 + H2SO4 = CaSO4 + 2HCl

б)
2Cu + O2 = 2CuO
CuO + 2HCl = CuCl2 + H20
CuCl2 + 2NaOH = Cu(OH)2 + 2NaCl
Cu(OH)2 = CuO + H2O
CuO + H2 = Cu + H2O
Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O
CuSO4 + Ba(OH)2 = Cu(OH)2 + BaSO4

Зоя06 A) 1)CaCo3=CaO+CO2
2)CaO+H2O=Ca(OH)2
3)Ca(OH)2+2KCl=CaCl2+2KOH
4)CaCl2+H2SO4=CaSO4+2HCl

б) 1)2Cu+O2=2CuO
2)CuO+NaCl=CuCl2+Na2O
3)СuCl2+H20=Cu(OH)2+HCl
4)Cu(OH)2=CuO+H2O
5)CuO=Cu+O2
6)Cu+H2SO4=CuSO4+H2
7)CuSO4+NaOH=Cu(OH)2+Na2SO4
