Suppose that the attractions are the dominant interactions between gas molecules, and the equation of state is p = nRT/v -n2a/v2. Derive an expression for the work of reversible, isothermal compression of such a gas. Compared with a perfect gas, is more or less work done on the surroundings when compression?

How many moles of air are there in a human lung with a volume of 2.4 l at stp? explain your answer

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
