Discoveries
Hydrogen is a gas that was discovered in 1766, by Henry Cavendish. Hydrogen is a colorless, odorless, tasteless gas. Hydrogen is considered important because hydrogen can be used to carry energy from its source to the place where it is required. Hydrogen is the lightest gas and most of hydrogen is found in water, very little found in fuel because of its light-weight.
Uses of Hydrogen:
1. "Town Gas" was a gas that many people in the towns use. It has a mixture of hydrogen, carbon monoxide, carbon dioxide and methane. 2. Synthetic fertilizer. This was used to help farmers grow large crops easier. 3. Water. 4. Hydrogen fuel. Hydrogen can make fuel for people. 5. Hot air balloons. 6. Delivery trucks(that are hydrogen powered). 7. Hydrogen energy. 8. Hydrogen gas. 9. Hydrogen power. 10. Air. When hydrogen is in air, it is combined with oxygen and many other elements and particles. |

Uses:
The most important single use of hydrogen is in the manufacture of ammonia. Ammonia is made combining hydrogen and nitrogen at high pressure and temperature in the presence of a catalyst. A catalyst is a substance used to speed up or slow down a chemical reaction. Ammonia is a very important compound. The most important product is fertilizer.
