Even though butanols have the same number of the same atoms, we see large differences in their ability to dissolve water. How do you account for this? How might you account for the much smaller differences observed among the pentanols?
In the experiment we recorded the solubility of alcohol in 1mL of water and of water in 1mL of the following 4 and 5 Carbon alcohols: 1-butanol, 2-butanol, 2-methyl-1-propanol, 2-methyl-2-propanol, 1-pentanol and 2-methyl-2-butanol.

A 3.5 L container is filled with gas at 1.00 atm. A piston then compresses the gas to 0.250 L. What is the new pressure
The enthalpy change for the oxidation of styrene, C8H8, is measured by calorimetry. C8H8(l) + 10O2(g) ? 8CO2(g) + 4HOH(l) ?rH = -4395.0 kJ/mol How much heat in kJ is required to oxidize 25.0 g of styrene?
How can one make five serial solutions of a stock solution of silver ion if the stock solution has a concentration of 0.100M, make a table of the volumes and solutions
Assuming ideal behavior, calculate the mole fraction of toluene in the solution.
When cobalt chloride is added to pure water, the CO ^2+ ions hydrate. The hydrated form then reacts with the Cl^- ions to set up equalibrium shown here
atomic absorption spectrometer was used with the method of standard additions to determine the concentration of cadmium in a sample of an industrial waste stream. For the addition, 10 uL of a 1000 ug/mL Cd standard was added to 10 mL of solution.
Find the standard enthalpy of formation of ethylene, C2H4(g), given the following data: heat of combustion of C2H4(g) = -1411 kJ/mol; ?H°f[CO2(g)] = -393.5 kJ/mol; ?H°f[H2O(l)] = -285.8 kJ/mol.
