How is atmospheric nitrogen converted into a biologically useful form of nitrogen?
frutty [35]

Answer:

The atmosphere is the largest reservoir of the nitrogen as it is composed of 78% of Nitrogen. Although 78%, this is not used by the organisms directly as the nitrogen molecule exists in nature in the form of divalent joined via triple bonds.

These triple bonds require a great amount of energy to be broken and used. Only a few prokaryotic organisms called nitrogen-fixing bacteria have the capability to break these triple bonds as they contain enzymes-nitrogenase complex which converts the atmospheric nitrogen to usable forms like ammonia, nitrates and nitrites. About 92% of the atmospheric nitrogen is fixed through this way rest through thunderstorms and Haber's process.

Thus, nitrogen-fixing bacteria is the answer.

Propane is burned to provide the heat in many cooking grills. The chemical
tangare [24]

Answer: it's 3CO2+4H2O+Energy

Propane is a linear alkane of formula C3H8. It is mainly used as fuel (this is the main component of liquefied petroleum gas) in cooking and chemical industry reactions.

The reaction of its complete combustion by the presence of oxygen is:

C3H8 (gas) + 5O2  ==> 3 CO2 + 4H2O + energy (2220⋅kJ)

As we can see, propane can release carbon dioxide and water as every combustion reaction, and a lot of energy in the form of heat.
