Q29 Santa Monica Big Blue Bus operates a fleet of CNG buses, which run on compressed natural gas (CNG), natural gas that has been compressed into a much smaller volume in the fuel tank. A newly designed CNG vehicle carries about several thousand cubic feet of compressed natural gas which contain 72 kg (kilograms) of carbon. If all of the natural gas is burned, how many kilograms of carbon dioxide will be emitted into the atmosphere? Assume no residue remains and the carbon dioxide is the only product in the combustion. If you are presenting this question, please explain the following: The steps in the calculation process O Please write out the steps involved in the conversion process including the units O Please explain how to operate on the units Please explain how to manipulate the powers of ten by hand (e.g. product rule and the quotient rule) How to apply the appropriate rule to the calculation: O addition-subtraction rule ("the decimal places rule"), OR multiplication-division…
