Question

Уксусная кислота реагирует с каждым из пары веществ, формулы которых: а) NH3 и ZN б) NaNO3 и Al2O3 в) С2Н5ОН и С6Н5ОН г) NO и Аg

Answer 1

Ответ будет А, а не В. так как с аммиаком получится амид уксусной кислоты, а с цинком - ацетат цинка.
А в пункте В есть фенол, с ним кислота не раегирует
Ответ: А

Answer 2

Chemical Reactions of Acetic Acid with Various Substances

Acetic acid (CH3COOH) is a weak acid that can react with different substances to form various products. Let's explore its reactions with the given pairs of substances:

a) NH3 and Zn: - Acetic acid reacts with ammonia (NH3) to form ammonium acetate and with zinc (Zn) to form zinc acetate. - The chemical equations for these reactions are: - With NH3: CH3COOH + NH3 → CH3COONH4 - With Zn: 2CH3COOH + Zn → (CH3COO)2Zn + H2.

b) NaNO3 and Al2O3: - Acetic acid does not react with sodium nitrate (NaNO3) or aluminum oxide (Al2O3) under normal conditions. - These substances remain unchanged when in contact with acetic acid.

c) C2H5OH and C6H5OH: - Acetic acid reacts with ethanol (C2H5OH) to form ethyl acetate and with phenol (C6H5OH) to form phenyl acetate. - The chemical equations for these reactions are: - With C2H5OH: CH3COOH + C2H5OH → CH3COOC2H5 + H2O - With C6H5OH: CH3COOH + C6H5OH → CH3COOC6H5 + H2O.

d) NO and Ag: - Acetic acid does not react with nitric oxide (NO) or silver (Ag) under normal conditions. - These substances remain unchanged when in contact with acetic acid.

In summary, acetic acid can react with ammonia and zinc to form specific products, while it does not react with sodium nitrate, aluminum oxide, nitric oxide, or silver under normal conditions.
