Notes:
Free hydrogen is rare because of the reactivity of this element. Hydrogen is not very reactive at room temerature but at higher temperatures it burns vigorously, and often explosively, in air or oxygen to form water. In the presence of a catalyst and under pressure hydrogen will combine with vegetable oils to form solid fats used as shortening, this process is known as hydrogeation. This process is extensivly used in the refining of oil products to increase the yields of gasoline. It's also commonly used to make ammonia and many other chemical substances. Other uses are to fuel rockets and in fuel cells to generate electricity.
