WebPart 1: Molar volume of oxygen (O 2) gas Oxygen will be produced by the decomposition of hydrogen peroxide: 2H 2 O 2 (l) 2H 2 O(l) + O 2 (g) The liquid reactant is 30 mL of a 3% hydrogen peroxide solution. The solid reactant is approximately 0.5 g of potassium iodide. (The potassium iodide is only a catalyst, not really a reactant.) WebThe oxygen passes into the atmosphere and the hydrogen joins with carbon dioxide to produce biomass. When living things need energy they take in oxygen for respiration. The oxygen returns to the atmosphere in the form of carbon dioxide. Oxygen gas is fairly soluble in water, which makes aerobic life in rivers, lakes and oceans possible.
