Question

В каких реакциях HCl окисляет? 1.HCl+MnO2= 2.HCl+Fe= 3.HCl+KOH=

Answer 1

Ответ:

2.

Объяснение:

Так как водород в этом соединение понижает свою степень окисления, с +1 - 0.

Answer 2

HCl can undergo different reactions, including oxidation reactions. Let's examine each of the reactions you provided:

1. HCl + MnO2: - In this reaction, HCl acts as a reducing agent, while MnO2 acts as an oxidizing agent. - The reaction can be represented as follows: 4HCl + MnO2 → MnCl2 + 2H2O + Cl2.

2. HCl + Fe: - In this reaction, HCl reacts with iron (Fe) to form iron(II) chloride (FeCl2) and hydrogen gas (H2). - The reaction can be represented as follows: 2HCl + Fe → FeCl2 + H2.

3. HCl + KOH: - In this reaction, HCl reacts with potassium hydroxide (KOH) to form potassium chloride (KCl) and water (H2O). - The reaction can be represented as follows: HCl + KOH → KCl + H2O.
