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

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 .

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

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.
