Question

2KMnO4 + Heat → K2MnO4 + MnO2 +___________​

Answer 1

Explanation:

2KMnO4 → K2MnO4 + MnO2 + O2 Given that the molecular mass KMnO4 is 158, what volume. 2KMnO4 → K2MnO4 + MnO2 + O2 Given that the molecular mass KMnO4 is 158, what volume of oxygen (measured at room temperature) would be obtained by the complete decomposition of 15.8 g. of potassium permanganate.
