A power plant generating electricity uses bituminous coal.

Coal Chemical Composition is below (percent by mass):

1) Neglecting Ash and water content, obtain the chemical representation of the coal used in this power plant in the form of:

2) Using above chemical representation, write the combustion reaction when complete combustion occurs at stoichiometric condition. Neglect elements with molar percentage less than 1%.
