A sample containing 17.5 moles of carbon monoxide (CO) has an initial volume of 22.4 L. What is  the final volume, in liters, when each of the following occurs and pressure and the temperature do  not change?  a) A leak allows one quarter of the CO molecules to escape from the container with 18.0 moles  of CO. b) Another 9.25 moles of CO gas are added to the container with the 18.0 moles of CO gas  already in it.

When the following reaction takes place inside a balloon, what will happen to the volume of the balloon as the reaction proceeds? Assume the pressure and temperature remain constant. Cl₂ (g) + H₂(g) → 2 HCI (g) The balloon gets smaller The balloon gets larger The balloon stays the same size
