Question

Explain combustion chemistry of carbon, methane and hydrogen 

Answer 1

i) Carbon: Burning of carbon to carbon dioxide ( complete combustion )

 

That means 1 kg of carbon needs 2.67 kg oxygen and produces 3.67 kg of carbon dioxide 

ii)Methane (CH4): 

Burning of methane with oxygen to carbon dioxide and water/ steam i.e. That means 1 kg of methane needs 4 kg of oxygen to produce 11/4 kg of carbon dioxide and 9/4 kg of water /steam

iii)Hydrogen:

 

The union of hydrogen with oxygen produces steam it is represented by the following equitation 1 kg of hydrogen combines with 8 kg of oxygen to produce 9 kg of steam.
