ETCH:
hey does anybody know what were the raw materials of nitrogen & hydrogen????

astarmathsandphysics:
Do you mean the matrial used to make nitrogen and hydrogen?

could be nitrogen from the air and either hydrocarbons or water to make hydrogen. Hydrogen and nitrogen are the raw material used to make ammonia.

Nitrogen from air

Hydrogen from Methane and Water reaction
