2.00 L H2 at 475 torr combines with 1.00 L N2 at 0.200 atm. Both are at 25 degrees C. (a) calculate the partial pressures of each of the gasses before reaction to produce ammonia, NH3...N2+3H2---> 2NH3 (b) calculate the moles of each gas before the reaction (c) determine the limiting reactant (d) calculate the moles of ammonia produced (e) calculate the partial pressures of all species in the system (f) the total pressure in the system
