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
