Question

What is the effect of temperature on the solubility of a gas? Increase in temperature decreases the solubility. Increase in temperature increase the solubility. Increase in temperature has no effect on the solubility. Which of the following expresses Raoult's Law? P = X P^0 P = X P^0 P = X P^0 A particular drug is naturally broken down in the body by a first-order process. The half-life of this drug is 2.5 days. If patient takes a 50.0 mg does, how many mg remain in the bloodstream after 240.0 hours? 25.0 mg 12.5 mg 6.25 mg 3.13 mg 1.56 mg A very dilute contains 116 mg of fructose (molar mass = 180, 16 g mol^-1) in 1.000 liters of solution. It is placed in an osmotic membrane if the temperature is 26.0 degree C? 3.36 torr 12.0 torr 151 torr 475 torr 1217 torr The Van't Hoff Factor, i, for two solutions of MgCl_2 of different concentrations were found to be 2.83 and 2.74. Which solution is more concentrated? Circle your answer: Solution with I = 2.74 Solution with I = 2.83 Which direction will the water flow? The two chambers are separated by a semipermeable membrane. Left right. To the left to the right. The term " colligative properties" refer to properties... of the solute, independent of the type to solvent as long as as it is nonvolatile and nonelectrolytic of the solvent, independent of the type to solute as long as as it is nonvolatile and nonelectrolytic Which has the higher boiling point? 0.8 m C_2H_5OH 1.6 m C_2H_5OH Neither (They are the same.) Consider the following system, which is exothermic in the forward direction. H_2(g) + I_2(g) 2HI H_2 and HI are colorless gases. I_2 is purple gas. If heat is added would you expect the mixture of gases to become more or less purple in color? more purple less purple no effect

Explanation / Answer

Solved first four problems, post one more question to get the remaining answers

11) The solubility of gas increase with the increase in temperature in case of organic solvents and it decrease with the increase in temperature if the solvent is water

Assuming the solvent is water, the answer will be Option A

Since both options are given and if it is multiple options can be correct, then correct answer will be A,VB

12) The correct answer is Option A

Psolution = xsolvent * P0(solvent)

13) half life = 2.5 days = 2.5 * 24 hours = 60 hours

Using the first order kinetics

ln(Ao/At) = kt

Half-life = ln2/k, which implies k = ln2/60

ln(Ao/At) = ln2/60 * 240 = ln16

At = Ao/16 = 50/16 = 3.125 mg

Hence the correct answer is Option D

14)

The correct answer is Option B, since vont hoff factor implies that the compound is easliy disintegrated and the ease of integration is increased by increase in vont hoff factor
