Question- Suppose 0.50g of pure water is sealed in an evacuated 5.0L flask and the whole assembly is heated to 60C. Will any liquid water be left in the flask or does all of the water evaporate?
It is not a question in the book, so I just need the full solution of deriving!

The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 10.0 L. How many moles of gas (n2) remain in the cylinder
When the following reaction is balanced in basic solution using the lowest possible whole number coefficients, the coefficient of H2O will be: CN-(aq) + MnO4-(aq) --> CNO-(aq) + MnO2(s)
At a certain temperature, Kw = 1 x 10-13. This means that pH + pOH = 13 at this temperature. Given this, what is the pOH of 0.05 M Ba(OH)2 at this temperature
Solubility of ionic compounds in water can either increase, or decrease with increasing temperature, or remain unchanged. Which property of a solute would allow you to predict the direction in which its solubility changes as temperature increases
A system undergoes a two-step process. In step 1 it expands adiabatically from 1.00 L to 2.56 L at 1.00atm external pressure. In step 2 it releases 73 J of heat at 1.00atm as it returns to the original internal energy. Determine the final volume o..
