Default chem math problems?

1) the weak electrolyte NH3 (g) does not obey Henrey's law. why? 02(g) obeys Henreys law in water but not in blood (an aqueous solution) why?2) Detergent molecules can stabilize the emulsion of oil in water as well as remove dirl from soiled clothes. A typical detergent is sodium dodexylsulfate, or sds, and it has a formulal of CH3(CH2)10CH2SO4 NA. In aqueous solution sds suspends oil or dirt by forming small aggregates of detergent anions called micelles. Propose a structure for micelles.3) An queous antifreeze solution is 40% ethylene glycol (C2H6O2) by mass. The density of the solution is 1.05%g/cm^3. Calculate the molality, molarity and mole fraction of the ethylene glycol.
