Ammonia gas is synthesized according to the balanced equation below.
N2(g) + 3 H2(g) -> 2 NH3(g)
If 2.50 L N2 react with 7.00 L H2, what is the theoretical yield (in liters) of NH3? Assume that the volumes of reactants and products are measured at the same temperature and pressure.
What are the annual CO2 emissions based on your vehicle use, vehicle's fuel consumption and a justified general combustion equation? Please use 10,000 miles as a reasonable estimate for annual vehicle use and use a published gas mileage for any sp..
Hydration of alkynes (via oxymercuration) gives good yields of single compounds only with symmetrical or terminal alkynes. Draw the major organic product(s) formed when hex-2-yne undergoes hydration in the presence of HgSO4 and H2SO4.
