LAws & VOLATILE LIQUIDS GAS EXTENSION Hydrogen Fuel Hydrogen gas is a possible fuel with great prospects A benefit of hydrogen gas over the typical hydrocarbon fuels is that the combustion hydrogen does not produce any carbon dioxide and, a more environmentally friendly choice. approach to produce the how to produce enough hydrogen gas the One hydrogen gas is to obtain it from the readily available resource of water. Flowers, Theopold and Langley, openstar.org The electrolysis of water, or water splitting, is achieved by applying electricity from a battery or other source to a sample of water molecules, breaking them into their component elements, hydrogen and oxygen, seen in the figure above. Because the hydrogen gas produced in this way is collected over water, it also contains water vapor from the water. You want to see how well this production method works and how much hydrogen gas you can produce. l. In lab, you set up a water electrolysis system similar to the one above with two collection tubes, one to collect the hydrogen gas and one to collect the oxygen gas. How will you be able to tell which colorless gas is which without the labels? Hint: the answer is in the I 19

Explanation / Answer

Answer:

1. Hydrogen is lighter gas than the oxygen, So H2 will appear at lower level than O2
