At 25 degrees C and 25.0 atm of pressure 3.00 liters of nitrogen is reacted with 4.70 liters of hydrogen gas at the same temperature and pressure. Find the volume of ammonia gas that will be obtained at the same temperature and pressure if the yield was 25.0 The unbalanced equation for the reaction is N2 + H2 rightarrow NH3 2. 0.252 g of Mg is added to120.0 ml of HCI solution in a coffee cup calorimeter where HCI was present in excess. It was found that the temperature of the solution in the cup went from 23.2 to 33.3 degrees C. Find the value of delta H for the following balanced equation Mg + 2 HCI rightarrow MgCl2 + H2. Assume that the specific heat of the solution in the cup is the same as that of water which is 4.184 J/mol K, that the density of the solution is the same as that of water which is 1.00 g/cm^3 and that the coffee cup itself has a heat capacity = 35.0 J/deg The atomic weight of Mg = 24.31
