Please help with question number 10. i apreciate it very much :)

Predict which of the following pairs of compounds would nol form a solution. The solubility of O2 (g), in water at 25degree C is 3.16 mL/100 g H20 when the gas pressure is maintained at 1 atm. What pressure in ati of O2 (g) would be required to produced saturated solution containing 10.9 mL/100 g H20? What is the minimum mass in grams of glycerol, C3H803 (MM = 92) that must be dissolved in 100. g H2O to prevent the solution from freezing at - 15degree C? (KrH20 = 1.86degree C m-1) (A) 74 (B) 66 (C) 10 (D) 7.4 (E) 114 The rate data below was obtained for the reaction, A (g) + 2 B (g) rightarrow C (g) + D (g). Determine the rate law for the reaction? Experiment Initial[A], Mol/L Initial[B], Mol/L Initial Rate 1 0.15 0.10 4.5x10-1 2 0.30 0.10 1.8 3 0.15 0.20 9.0x10-1 (A) rate = k [A] (B) rate = k [A][B] (C) rate = k [A]2[B] (D) rate = k[A]2[B]3 (E) rate = k [A][B]2

Explanation / Answer

(c) rate = k[A]2[B]
