Consider a 100 mL aqueous standard solution containing 100 μg/L of iodomethane that is stored in a well sealed 1 L flask (i. e., 900. mL of air). The following data is provided for iodomethane;

Po = 53,700 Pa, Cw Sat = 0.0977 mol L-1, KH = 542 Pa m3 mol-1

a) Calculate the concentration of iodomethanein the water and headspace of the bottleat equilibrium at 25°C.

b) If the bottle is opened after equilibration and all of the air in the headspace is flushed out and replaced by fresh air, what will the concentration of iodomethane be in the aqueous solution after the equilibrium is re-established?

c) Calculate the fraction of iodomethane present in the liquid water of a cloud aerosol characterized by VH2O(l)= 0.10 mL per 100. L air. How will your answer change if the temperature is 5°C?

Iknow the answer is a but i don't know why

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.
