45. A solution has [OH-] = 3.0x10-7 M. The [H+] in this solution is (A) 1.0 M (B) 3.0 x 10-7 M (C) 1.0 x 10-7 M (D) 3.3 x 10-8 M (E) none of these

46. What is the pH of a 2.1 M solution of HNO3?(A) –0.32 (B) 0.32 (C) 14.32 (D) 13.68 (E) none of these

47. Given the reaction \( A(g) + B(g) \rightleftharpoons C(g) + D(g) \). You have the gases A, B, C, and D at equilibrium. Upon adding gas A, the value of K (A) increases because when A is added, more products are made, increasing the product-to-reactant ratio (B) decreases because A is a reactant, so the product-to-reactant ratio decreases (C) does not change because A does not figure into the product-to-reactant ratio (D) does not change as long as the temperature is constant (E) depends on whether the reaction is endothermic or exothermic

48. Given the equation A(g) $\rightleftharpoons$ B(g) + 2C(g). At a particular temperature, $K = 1.3 \times 10^5$. If you mixed 1.4 mol B, 0.050 mol C, and 0.0050 mol A in a 1-liter container, in which direction would the reaction initially proceed? (A) The reaction will proceed to the right. (B) The reaction will proceed to the left. (C) The mixture is at equilibrium. (D) More information is needed to answer the question.
