с какими из перечисленных веществ реагирует уксусная кислота?
Fe, KHCO3, Na2O, Cu, SO2, LiOH

Ответ:

KHCO3 + CH3COOH → CH3COOK + H2O + CO2

2 Fe + 6 CH3COOH = 2 Fe(CH3COO)3 + 3 H2

2CH3COOH + Na2O = 2CH3COONa + H2O

2Cu + 6CH3COOH = 2Cu(CH3COO)3 + 3H2

CH3COOH + LiOH = H2O + LiCH3COO

Ответ:

CH3COOH+Fe=H2+Fe(CH3COO)2

CH3COOH+KHCO3≠

CH3COOH+Na2O=2H2O+Na2OC2

CH3COOH+Cu=H2+Cu(CH3COO)2

CH3COOH+SO2≠

CH3COOH+LiOH≠
