4. coal is mostly carbon. when it is burned it reacts with molecular oxygen (o2) in a combustion reaction to produce carbon dioxide. write out a balanced chemical equation for the combustion of coal. include states.5. approximately 0.15% of the electricity generated used coal period on average, each person combust 37.5 kg of coal per year to generate the electricity that they use. based on this information and the balanced chemical equation in question 4, calculate how many pounds of carbon dioxide you produce from coal per year. 1 kg equals 2.2 pounds. show your work.
