AMMONIA
NH3 Producing Ammonia The Main Uses of Ammonia Is Ammonia Safe? Why is Ammonia Produced? Is the Production of Ammonia Environmentalty Friendly? "Ammonia is one of the most wiedly produced chemicals in the world"(unite 4 chemestry at work). Explosives: Fertilisers:
Fertilisers is the number one use of Ammonia!!! Two most commonly used firtilisers are: Ammonium Sulphate -> (NH4)2SO4:

The reaction of ammonia and sulfuric acid produces:
ammonium sulfate
2NH4OH(aq) + H2SO4(aq) <-(reversable reaction)-> (NH4)2SO4(aq) + 2H2O(l) Ammonium Nitrate ->NH4NO3:

The reaction of ammonia and nitric acid produces:
ammonium nitrate
NH4OH(aq) + HNO3(aq) <-(reversable reaction)-> NH4NO3(aq) + H2O(l) Ammonia was firstly used in WW1 in order to make explosive weapons and is still used in this industry today!!! Other Ammonia based products: Refrigeration of chemicals and plastic (15%).
Zinc and NIckel extrasction (10%).
Cleaning products. Other Fertilisers:
'Nitro - Chalk'.
Ammonia
Calcium Nitrate.
Calcium Cyanamide.
Urea.
Sodium NItrate Proparties of Ammonia Production process of Ammonia The Haber Process Fritz Haber (1868 - 1934) Ammonia is produced when combining Nitrogen and Hydrogen gas together. Bibliography:

Fritz Haber:
Invented the process of producing ammonia.
During WW1 developed the poisoned gas. YES!! The process in which nitrogen and hydrogen react in order to form Ammonia:
N2(g) + 3H2(g) <-(reversable reaction)-> 2NH3(g) Ammonia has a strong smell very soluble in water:
becase it if formed from hydrogen bonds.
Problems with Ammonia Production: equilibrium = temperature vs rate energy
poision
waste
health and safty -> most not be enhiled.
high pressure -> leaking management.
equipment failure
