Suppose that you have a gas confined to a cylinder with a movable piston. Determine how you would need to change the height of the piston to increase the pressure inside the cylinder while keeping the temperature constant? You would need to increase the height of the piston. You would need to decrease the height of the piston. The height of the piston would remain the same. Determine how the height of the piston would change when you increase the gas temperature inside the cylinder while keeping the pressure constant. The height will decrease. The height will increase. The height will remain the same.

Y=‐1x + 7 if y has a value of ‐24 what is the value of x?

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
