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

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

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
