Just how much water and carbon dioxide does the combustion of fossil fuels produce?

1kg of fuel contains this mass of       C (kg) 1kg of fuel contains this mass of H (kg) 1kg of fuel produces this mass of H2O (kg) 1kg of fuel produces this mass of    CO2(kg) 1kg of fuel requires this mass of    air (kg) Hence this mass of Oxygen is consumed        O2 (kg)
Fuel type
Natural gas 0.71 0.23 2.03 2.59 16.02 3.68
Liquid (ave No.1,2,6 & Gasoline) 0.86 0.14 1.22 3.13 14.62 3.36
Coal 0.66 0.04 0.36 2.40 8.97 2.06

Notes:

1) The sum of constituents is not 1.0 because of other compounds not taken into account (eg. Ash)

2) Factors from ‘heat_generators_1’ https://mail-attachment.googleusercontent.com/attachment/u/0/?ui=2&ik=e879a423c9&view=att&th=1639fd76f5ffdc9e&attid=0.1&disp=inline&realattid=1639fd75160493e6f251&safe=1&zw&saddbat=ANGjdJ-

3) Constituents are taken from from ‘Chapter 3 Fuels and Combustion’ https://mail.google.com/mail/u/0/?tab=wm#search/chapter+3+fuels+and+/1639fc39344def75?projector=1&messagePartId=0.1. They may vary from the values used in the main article.

4) The O2 IS CONSUMED – it is added to either C or H to produce water or carbon dioxide. That is, the oxygen is no longer – it has been combined with other compounds to form new compounds.

5) Likewise 1kg of fuel produces more than 1kg of products because oxygen has been ADDED to the C and H.
