WebIn order to determine whether a gas sample is hydrogen or oxygen you can light a smoldering toothpick into the gas. If an explosion happens then the gas is likely to be hydrogen and if the ﬂame errupts then it is likely to be oxygen. 5. Outline the procedures you would use to determine whether a gas sample was composed of hydrogen or oxygen. 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.
