1)С2H6-----Ni,t----->C2H4+H2
2)C2H4+H2----Ni,t------>C2H6
C2H6+Cl2-----hv----->C2H5Cl+HCl
3)C2H5Cl+KOH-----H2O,t----->C2H5OH+KCl
4)C2H5OH+[O]----->CH3COOH
NH2OH + HOOC-CH3 = NH2-CH2-COOH + H2O
CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4
n(NaOH) = 2 моль
n(Cu(OH)2) = 1 моль, М(Cu(OH)2) = 98 г/ моль, m=98 г
3моль NaOH - m Cu(OH)2
2 моль - 98 г
m(Cu(OH)2) = 147г
