A NEWLY invented metal compound can loosen the chemical bonds of the nitrogen molecules that make up four-fifths of the atmosphere
- Ngo Thien Quy on 14 Feb 13
  
  In our atmosphere, the reactions between nitrogen and oxygen are in dynamic equilibrium where they continue to react. Surprisingly, nitrogen seems to be more abundant than oxygen is.

it must first be converted into ammonia (N[H.sub.3]), using an industrial process called Haber-Bosch, in which an iron catalyst is used to crack open the triple bond of the nitrogen molecule, at high temperature and pressure
- Ngo Thien Quy on 14 Feb 13
  
  Nitrogen is basically unnecessary when it hasn't been broken down or reacted, becuase the nutrients from nitrogen are not able to be used.

Ammonium salts of oxidizing anions--nitrate, dichromate, and perchlorate--are unstable and can explode or deflagrate when heated
- Ngo Thien Quy on 14 Feb 13
  
  Ammonia is NH3, but ammonium NH4. I believe the structure of ammonia is trigonal pyramidal and then ammonium has a structure of tetrahedral.

A large ammonia plant might have as much as 100 tons of catalyst.
- Ngo Thien Quy on 14 Feb 13
  
  If the ammonia plant has such a large amount of catalyst, the reaction of creating and decomposing ammonia would be ongoing and occur much more quickly compared to how it would've reacted without a catalyst.

  our class is going to learn about the Ostwald process, like read about it, correct?
