A chemistry student in lab needs to fill a temperature-control tank with water. The tank measures 34.0 cm long by 17.0 cm wide by 14.0 cm deep. In addition, as shown in the sketch below, the student needs to allow 2.0 cm between the top of the tank and the top of the water, and a round-bottom flask with a diameter of 11.5 cm will be just barely ...

A flask equipped with a valve contains 3.0 mol of H 2 gas. You introduce 3.0 mol of Ar gas into the flask via the valve and then seal the flask. a What happens to the pressure of just the H 2 gas in the flask after the introduction of the Ar? If it changes, by what factor does it do so? b How do the pressures of the Ar and the H 2 in the flask ...
