If the combustion of coal in power plants is a significant source of oxides of sulfur (SO2) and oxides of nitrogen (NO2), what will happen to the relative amounts of each produced if coal was instead burnt in pure oxygen? Assume no other changes are made and the
furnace operates at the same temperature?

your answer would be “dry”

the correct answer is:

a. formation of precipitation

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
