What will be the final pressure of the system after after the reaction is complete?
Ammonia, NH3(g), and hydrogen chloride, HCl(g), react to form solid ammonium chloride, :NH3(g) + HCl(g) ----> NH4ClTwo 2.00 flasks at 30.0 are connected by a stopcock, as shown in the drawing. One flask contains 5.20g NH3(g), and the other contains 4.40g HCl(g). When the stopcockis opened, the gases react until one is completely consumed. What will be the final pressure of the system after the reaction is complete? (Neglect the volume of theammonium chloride formed.)
