Question

Which of the following is the balanced equation for the decomposition of hydrogen peroxide (H2O2) into water and oxygen gas?

A. H2O2 --> 2H + 2O
B. H2O2 --> H2O + O2
C. 2H2O2 --> H2O + 2O2
D. 2H2O2 --> 2H2O + O2

Answer 1

The correct balanced equation for hydrogen peroxide decomposition is 2H2O2 --> 2H2O + O2, following the law of conservation of matter.

Step-by-step explanation:

The correct balanced equation for the decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2) is: 2H2O2 --> 2H2O + O2. This reaction adheres to the law of conservation of matter, meaning no atoms are created or destroyed during the chemical change. The balanced equation ensures there are equal numbers of each type of atom on both sides of the equation, with four hydrogens and four oxygens present in the reactants and products.
