Find the amount ofNO2 that must be added to 2.3mol ofSO2 in order to form 1.3mol ofSO3 at equilibrium.The equilibrium constant for the reactionSO2(g)+NO2(g)?SO3(g)+NO(g) is 3.1.
Nevertheless in more concentrated solutions part of nitric acid is present as un-ionized molecules of HNO3. For instance in a 50% solution (7.5M) at 25 C merely 33% the molecules of HNO3 dissociate into H+ and NO3-. Explain what is the value of Ka..

Why is it that benzyl ethyl ether is named as an ether, but 3-chloro-1-ethoxybenzene has the same ether group, yet the group is named as an ethoxy instead?
The flasks is opened, and the gases are allowed to mix thoroughly, the following reaction proceeds at constant temperature. What is the resulting total pressure of gases in now-joined flasks after the reaction proceeds to completion
14.0 moles of gas are in a 8.00 Liter tank at 21.0 Celcius. Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane are a= 2.300L^2 x atm/mol^2 and b=.0430 L/mol.
