Объяснение:

CaO + 3C -> CaC2 + CO↑ (t)

CaC2 + 2H2O -> CH=-CH + Ca(OH)2

CH=-CH + H2 -> CH2=CH2  (t, kat)

CH2=CH2 + H2O -> CH3-CH2-OH (kat)

C2H5OH + 3O2 -> 2CO2↑ + 3H2O

CO2 + 2NaOH = Na2CO3 + H2O

Na2CO3 + 2AgNO3 ->2 NaNO3 + Ag2CO3↓

CH=-CH + H2O-> CH3COH

CH3COH + Ag2O -> CH3COOH + 2Ag↓

CH3COOH + NaOH -> CH3COONa + H2O
