The catalytic converter in an automobile changes harmful gases produced during fuel combustion to less harmful exhaust gases. Nitrogen dioxide (NO)) reacts with carbon monoxide to form nitrogen gas and carbon dioxide according to the reaction below. It takes approximately 20 minutes for 8
moles of nitrogen dioxide to react. This process uses the metal, platinum, as a catalyst in the reaction. Since the cost of this precious metal has
increased recently there have been many thefts of catalytic converters to recover the platinum. The added cost of the vehicle has certainly resulted in
cleaner emissions from tailpipes.
2NO2(g) + 4CO) - N2(0) + 4CO2(g) + 1198.4 KJ
Show the correct numerical set-up for determining the moles of CO2 produced when 8 moles of nitrogen dioxide are used. Then calculate your
answer

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
