A2.00 liter plastic container is flexible enough that its volume can change even while it's sealed. if the container has an initial temperature of 25 °c, what will the new volume be if you put it in the freezer, at -4.0 °c? assume the pressure of the air inside remains constant.

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.
