Question

Potassium permanganate (KMnO4) reacts with hydrochloric acid (HCl) to form potassium chloride (KCl), manganese chloride (MnCl2), water (H2O), and chlorine gas (Cl2). The balanced chemical equation is 2KMnO4 + 16HCl → 2KCl + 2MnCl2 + 8H2O + 5Cl2. Select the correct ratios of each of the following substances.

Step-by-step explanation:

Answer 2

Balanced chemical reaction:

2KMnO₄ + 16HCl → 2KCl + 2MnCl₂ + 8H₂O + 5Cl₂.

1) According to balanced chemical reaction:

n(KMnO₄) : n(KCl) = 2 : 2 (1 : 1).

Two molecules of potassi chloride are formed from two molecules of potassium permanganate.

2) According to balanced chemical reaction:

n(HCl) : n(H₂O) = 16 : 8 (2 : 1).

3) According to balanced chemical reaction:

n(KMnO₄) : n(Cl₂) = 2 : 5.

4) According to balanced chemical reaction:

n(HCl) : n(MnCl₂) = 16 : 2 (8 : 1).
