the molecule iodine monochloride ICl has a diple moment of 1.6 D and a bond length of 2.32 A. What is the effective charge on I in untis of electronic charge e?
In a coffee-cup calorimeter, 1.50 g of NH4NO3 is mixed with 76.0 g of water at an initial temperature of 25.00°C. After dissolution of the salt, the final temperature of the calorimeter contents is 23.65°C.
Suppose 25.0 g of solid NaOH is added to 1.5 L of an aqueous solution that is already 2.4 M in NaOH. Then water is added until the final volume is 4.00 L. Determine the concentration of the NaOH in the resulting solution.
At what wavenumber would you expect to see an absorbance in the IR if your sample contained water as an impurity?

A certain quantity of a gas occupies 61.3 mL at 68 ?C. If the pressure remains constant, what would be the volume of the gas at 128 ?C?
calculate the equilibrium constant from an absorbance value but my professor never told us how to calculate this.
A sample of hydrogen gas was collected over water at 36°C and 855 mm Hg. The volume of the container was 6.50 L. Calculate the mass of H2(g) collected. (Vapor pressure of water = 44.6 torr at 36°C)
Suppose that a sample of gas occupies 192 mL of volume at 25C and a pressure of 206 torr. What would be the volume if the pressure were changed to 506 torr at 25C.
In order to understand the prehistory of the Hawaiian island of Lana'i better, anthropologists Maria Sweeney, Melinda Allen, and Boyd Dixon used radiocarbon dating on charcoal found in an ancient dwelling site, the Kaunolu Village National Histor..
the forensic technician at a crime scene has just prepared a luminol stock solution by adding 11.0 of luminol to creating a solution with a total volume of 75.0 . What is the molarity of the stock solution of luminol?
hat conclusions can you make concerning the size of the central atom X and the X-H bond length? Compare the four models of CHBrICI. Are they all the same (superimposable on each other? If the answer is yes, can you construct any that are not the s..
