1) How to classify the form of sodium sulfate decahydrate and potassium

acetate  which one is     efflorescent and which one is deliquescent ?

2) Use the phase diagram of Substance X below to find the temperature at which X turns to a gas, if the pressure above the solid is 0.33atm.
Note: your answer must be within 12.5°C of the exact answer

3) You have an unknown molecule with a molecular formula C5H8. The most

acidic proton has a pKa of about 25. Draw a plausible structure for this molecule, and label the most acidic proton with its pKa value.

4) Oxygen and nitrogen are mixed together. The total pressure of the gases

is found to be 700 torr. Oxygen's partial pressure equals 300 torr. What is nitrogen's partial pressure?
