Oxygen can be produced by the decomposition of hydrogen peroxide (H2O2). What is the equation for this reaction?
2H2O2 = O2 +2H2O
H2O2 = 2O + H2
2H2O2 + CO2 = HCO3 + H2 + H2O

Oxygen can be produced by the decomposition of hydrogen peroxide (H2O2). What is the percentage of oxygen in air at atmospheric pressure
Other elements can combust in oxygen. Write a balanced equation for the combustion of sulphur.
S + O2 = SO2
S + O2 = SO4
S + O2 = SO + H2O
SO2 dissolves in rainwater to form an acidic solution.
