Question

When broken down by its enzyme, hydrogen peroxide yields:

a) Water and oxygen
b) Carbon dioxide and water
c) Hydrogen and oxygen
d) Carbon monoxide and water

Answer 1

The decomposition of hydrogen peroxide (H2O2) yields water (H2O) and oxygen gas (O2).

Step-by-step explanation:

The decomposition of hydrogen peroxide (H2O2) yields water (H2O) and oxygen gas (O2). This is represented by the balanced chemical equation:

2H2O2 → 2H2O + O2

The breaking of the chemical bonds between the hydrogen and oxygen atoms in hydrogen peroxide results in the formation of new bonds between hydrogen and oxygen to form water, and between the oxygen atoms to form oxygen gas. This decomposition reaction is catalyzed by the enzyme catalase.
