The ... :1- Nitrogen is obtained from the air. 2- Hydrogen obtained from reaction of methane with steam. 3- Passed over iron catalyst at 450 degrees and 200 atmospheres. 4- Reaction is reversible. Some ammonia turns back into hydrogen and nitrogen

Haber Process

... is used to create nitric acid and is reacted with oxygen and water. ... salts can be produced by reacting ... with different acids. The reaction is carried out differently in the lab and in industry. Reaction is for the source of Nitrogen

Ammonia

6 of 11

Reaction for Nitrogen: Ammonia + ... -> Ammonium Nitrate

Nitric Acid

7 of 11

Reaction in ... : Reaction carried out in giant vats at high concentrations resulting in exothermic reactions. heat released evaporates water

Industry

8 of 11

Reaction in ... : Smaller scale with titration and crystallisation. Lower concentration so less heat is produced and it's safer for the person carry out the reaction. Crystallisation gives pure Ammonium Nitrate crystals

the lab
