Gaseous ammonia reacts with oxygen gas to produce gaseous nitrogen monoxide and liquid water. If 750 grams of ammonia and 750 grams of oxygen gas were mixed, what maximum mass of nitrogen monoxide could be produced
If you have 1 gram of (-) ethyl lactate and purify it with an enantiomeric excess of 85% yields, wihout any loss of material. How many grams of the (+) enantiomer were separated?
Under what conditions would you expect a real gas to be (a) more compressible than an ideal gas; (b) less compressible than an ideal gas
One reason you do this is to help minimize the potential side reaction that forms byphenyl. How does the additional 30 mL of anhydrous diethyl ether minimize the formation of the biphenyl side product?
Calculate the change in pH when 6.00 mL of 0.100 M NaOH(aq) is added to the original buffer solution.
Consider a system with four energy levels: 0E, 1E, 2E, 3E, where E is kT (E can be represented by epsilon and T is 100K). Assume that there are 10 particles. Provide an expression for energy, heat capacity and entropy. Plot all as a function of T
