The products generated in the operation of real automobile engines include various oxides of nitrogen, and it is desirable to remove these compounds from the exhaust stream, rather than releasing them

into the atmosphere. Currently this is done by the "catalytic converter," but other technologies are being explored. One possible method involves the use of isocyanic acid, HNCO, which reacts with NO₂ to produce N₂, CO2, and H₂O, as shown in the equation below. 8 HNCO +6 NO27 N2 + 8 CO2 + 4H₂O What mass of HNCO (in kg) would be required to react completely with the estimated 8.40 x 107 kg of NO2 produced each year by automobiles in Louisiana? kg Submit Answer Retry Entire Group 9 more group attempts remaining
