Hydrogen Peroxide - H2O2
Hydrogen peroxide (H2O2) is a kind of chemical. A molecule
of hydrogen peroxide has oxygen and hydrogen atoms
in it. Hydrogen peroxide is a clear liquid.
Hydrogen peroxide is in some liquids that are used to clean wounds.
There is a small amount of hydrogen peroxide in Earth's
air. Hydrogen peroxide helps change sulfur
trioxide (SO3) in the atmosphere into sulfuric
acid (H2SO4). Sulfuric acid is part of acid
