Consider: C7H16 (l) + 11 O2 (g) → 7 CO2 (g) + 8 H2O (l) ΔH°reaction=- 4130 kJ. How much energy is released when 4.000 moles of C7H16, is combusted?
Methylbenzene and 1,2-dimethylbenzene mix to form an ideal solution. At 90oC, the vapor pressure of pure methylbenzene is 400 Torr and that of pure 1,2-dimethylbenzene is 150 Torr.
Determine How hot should be the air in a ballon be heated if it has initially a volume of 750. L at the temperature of 20 degree celsius and the final volume must be 1,000.l
KEtones also undergo the aldo condensation, although a succesful reaction often requires "enhanced" conditions, since the addition involves an unfavorable equilibrium constant.
4NH3 + 5O2 yields 4NO + 6H2O Given 1.50g of NH3 reacts with 2.75g of O2 which is the limiting reactant?

What is the cell potential at each of the given volumes as a. 5.00 mL,b. 12.00 mL,c. V equilvalence pointd. 48.00 mL of added Ce4+?
Sodium methoxide CH3ONa is a weaker base than BuLi or nBuLi butyllithium. Recommend an explanation why it is not surprising to find that a weaker base is sufficient to prepare the Horner-Emmons-Wittig reagent.
The blue color of the sky is due to the scattering of sunlight by the molecules in the air. The blue light has a frequency of about 7.5 x 10^14 Hz.
A 2.154 g sample of HgO produces 125 mL of oxygen gas. The gas is collected over water at 24 C and an atmospheric pressure of 763 torr.
