When X is heated with manganese (IV) oxide, oxygen is produced X is
Answer Details
The substance X reacts with manganese (IV) oxide when heated, and produces oxygen gas. Among the options given, the only substance that fits this description is KCIO3, also known as potassium chlorate. When potassium chlorate is heated with manganese (IV) oxide, the following chemical equation takes place: 2KClO3 → 2KCl + 3O2 In this equation, manganese (IV) oxide acts as a catalyst, which means it helps to speed up the reaction without being consumed in the process. The result is the production of oxygen gas, which is released as a byproduct. Therefore, the answer to this question is KCIO3 (potassium chlorate).
