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.)

A sample of an ideal gas at Pi is initially confined to one chamber of the apparatus represented above, and the other chamber is initially evacuated. The valve connecting the chambers is opened, and the gas expands at constant temperature to fill both chambers. Which of the following best describes AS for the process? A. S < 0 because the pressure of the gas decreases by half. B. S = 0 because there is no change in the total number of particles of the gas. C. S = 0 because the average kinetic energy of the gas particles is unchanged. D. S > 0 because the gas particles become dispersed in a larger volume.
