How many unpaired electrons will there be in a high-spin octahedral complex of Fe(II)
Assume that the volume of Earth's oceans is 137 x 10^7 km^3 and that the density of seawater is 1.03 g/cm^3. Also assume that the heat capacity of seawater is the same as that of water.
How many liters of softened water, containing a sodium concentration of 5.8×10^-2% sodium by mass, have to be consumed to exceed the FDA recommendation (less than 2.4 g sodium per day)? (Assume a water density of 1.0 g/mL.)
Which of the following compounds contains a chiral carbon molecule? a) chloroethane b) 1,1-dichloroethane c) dibromochloromethane d) 2-butanol
Calculate the final temperature when a 16.4 gram sample of ice at 0oC is placed into a styrofoam cup containing 126 grams of water at 72.7 oC. Assume that there is no loss or gain of heat from the surroundings.
what is the concentration of H2 in the water in grams per milliliter? (See Appendix G in your textbook for the vapor pressure of water.)
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?

What are the mole fractions of C6H6 (x1), C3H6 (x2), O2 (x3) and N2 (x4) in the fresh feed stream. What is n6, the molar flow rate of the recycle stream
What is the role of sodium sulfite in the experimental procedure of the creation of Benzoic acid. -I know that it breaks down any remaining bleach that did not react, but can someone please explain how it works
A 10.1 g sample of CaCl2 is dissolved in 119 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C·..
