Nitrogen is not involved in the combustion reaction. It can be calculated on the basis of the number of oxygen moles.
Dear AWK,
So, what I realized that even if I remove Nitrogen, it is not affecting Oxygen molecules in any way, the only difference I got in the reaction equation is the ''total'' value in ''kg'' got reduced because of elimination of Nitrogen and still the CO2 is more than 8 Kg. I think that is the only way to do reaction equations.
But atleast tell me whether the procedure I did for calculating reactions is correct or not ? It is more important to know for me at the moment, if I am calculating wrong, I can correct it.
And to calculate flame temperature, do I have to add these ''total'' values from all 3 equations together ??
Kind regards
