At 25 °C and 795 Torr, carbon dioxide has a solubility of 0.0356 M in water. What is its solubility at 25 °C and 2030 Torr?
The pH would decrease slightly. The pH would decrease dramatically. The pH would increase slightly. The pH would increase dramatically. The pH would not change at all.
Given a 4.50 L container of helium at 298 K and 1.00 atm, and a 3.00 L container of argon at 298 K and 1.00 atm, write a brief statement to explain whether or not atoms of He and Ar in their respective containers have the same average speed.
A fire occurred in a storage room where a steel cylinder of oxygen-enriched air was kept. The pressure of the gas in the cylinder was 300 atm at 20 C.
Extract a solute from 100 mL of water using only 300 mL of ether. The partition coefficient between ether and water is 3.0. Calculate q, the fraction of solute that would remain in the water under each of the following extraction conditions
Suppose 50 mL of 0.020 M Hydhrochloric acid solution was mixed to 50 mL of 0.20 M acetic acid solution (Ka of acetic acid, CH3COOH, = 1.8 x 10-5). Determine the approximate pH of the mixture.
