40.0 g of ammonia (NH3) and 40.0 g of oxygen gas are made to react at 200ºC until all of the limiting reactant is used: NH3(g) + O2(g) → N2(g) + H2O(g) 4NH3 + 3O2 → 2N2 + 6H2O a) Determine the limiting reagent. b) Find the moles of water vapour produced. c) For the reactant that is in excess, calculate i - the amount of this reactant not consumed by the reaction. ii – the volume (at STP) of excess reagent left at the end of the reaction.
