Calculate the work done during the isothermal reversible expansion of a van der Waals gas. Account physically for the way in which the coefficients a and b appear in the final expression.
an experiment shows that a 247ml gas sample has a mass of 0.432 gas at a pressure of 752 mmhg and a temperature of 28c.
Consider a 0.20 M NH3/0.20 M NH4CI bufffer. 0.002500 mol of HCI is added to 65.0 mL of the buffer. How many moles of NH3 and NH4+ remain once the solution has equilibriated. The ka for the equilibrium is 5.6 x 10-10
