The balanced equation for the reaction of nitrogen and hydrogen that yields ammonia is N2 +3H2 produces 2NH3. This equation means that it requires one molecule of nitrogen gas to react with three molecules of hydrogen gas to form two molecules of ammonia.
Ammonia is a compound that is colorless and has a pungent odor. Its boiling point is -28.03 degrees Fahrenheit, while its melting point is -107.86 degrees F. The molecular weight of NH3 is 17.03 grams per mole. Some applications of ammonia are for fertilizers in the form of urea and in the production of explosives. Ammonia is a hazardous substance. When people are exposed to it, ammonia can cause irritation to the throat, eyes, skin and lungs.
