Question

The reaction below can be catalyzed by manganese dioxide (MnO2). If you carried out such a reaction, which compound would you expect to find in the reaction container at the end of the reaction?
2H2O2 ?2H2O + O2

A. MnO

B. MnH2

C. MnO2

D. MnOH

Answer 1

Answer:

$\boxed{\text{C. MnO _{2} }}$

Explanation:

2H₂O₂ ⟶ 2H₂O + O₂

A catalyst is a substance that speeds up a reaction but can be recovered unchanged at the end.

Thus, at the end of the reaction I would expect to find H₂O and MnO₂ in the container.

Water is not listed in any of the options, so I will have to choose $\boxed{\text{C. MnO _{2} }}$.

A, B, and D are wrong. They are not reactants, products, or catalysts.
