Question

Chlorine atom

10. What does the following equation represent; 2KMnO4 -> K2MnO4 + MnO2(s)
+ O2(g) ?*
A. Oxygen turned in to carbon dioxide
B. Sulphate and lithium boiled
C. Decomposition of potassium permanganate(Heating)
D. None of the above​

Answer 1

C. Decomposition of potassium permanganate(Heating)

Step-by-step explanation:

The equation of the reaction is given as;

2KMnO4 -> K2MnO4 + MnO2(s) + O2(g)

Reactant = 2KMnO4

Products = K2MnO4 + MnO2(s) + O2(g)

A. Oxygen turned in to carbon dioxide

Incorrect option - Oxygen is not the reactant

B. Sulphate and lithium boiled

Incorrect option - Sulphate and lithium are not part of this reaction

C. Decomposition of potassium permanganate(Heating)

Correct option - potassium permanganate decomposed to form K2MnO4 + MnO2(s) + O2(g)

D. None of the above

Incorrect option
