A 50.0 ml sample of benzene at 16.9 degrees C was cooled to its melting point, 5.5 degrees C and then frozen. How much heat was given off in this process? The density of benzene is 0.80 g/ml. Its specific heat capacity is 1.74 J/gK. Its heat of fusion is 127 J/g.
Suppose that two equal volumes of 0.2 molar NaCl (aq) solutions are separated by a membrane and that the left -hand compartment of the experimental arrangement contains a polyelectrolyte molecule Na6P at a concentration of 50 g/liter
the solubility in water is 8.7 g per 100 mL at 20 degrees C and 34.2 g per 100 mL at 100 degrees C. Write the equation for the solubility equilibrium, including heat as a reactant or product. What is the sign of DeltaH of the solution
If one collects the first liter of gas that moves from the original room into the evacuated room, approximately what would you expect its composition to be? Would it be the same as regular air?
A sample of neon gas used in a neon sign occupies a volume of 1.70 L at a pressure of 580 torr. Calculate the volume of the gas if the pressure in the glass tube of the sign is 781 torr.
The nitration of toluene gives o- and p-nitrotoluene as the major products. Please explain this observation, using structures (rather than words) as much as possible.
