The Kingston Steam Plant burns 14,000 tons of coal each day and generates 1010 kilowatts-hours of electricity each year (enough for 700,000 homes). Coal is primarily carbon which undergoes combustion in the following reaction:
C(s) + O2 (g) -> CO2(g)
How many grams of oxygen is required for the combustion of 1 day's coal?How much carbon dioxide is produced each day?
