1. Ammonia and hydrogen chloride react to form solid ammonium chloride: NH3 (g) + HCl(g) → NH4Cl (s) Two 1.50 L flasks at 20.0 °C are connected by a valve, as shown in the drawing below: 3.00 g 1.50 L 20.0 °C NH3(g) HCl(g) 3.00 g 1.50 L 20.0 °C The flasks contain 3.00 g of NH3 (g) (MM = 17.0 g/mol) and 3.00 g of HCI (g) (MM = 36.5 g/mol), respectively. When the valve is opened, the gases react until one is completely consumed. (a) As soon as the gases mix, before they react, what will be partial pressure of HCI (g)? (b) Which gas will remain in the system after the reaction is complete? Calculate its grams. (c) At the end of the reaction, the contents are cooled in a refrigerator at 4.0 °C. What will be the final pressure of the system? (Neglect the volume of the ammonium chloride formed.)
