Chem Help Please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!?

13. What is the [H+] of a solution with a pH of 5.6? Use a scientific calculator.(Points: 3) 5.0 × 105 8.3 × 106 2.5 × 106 7.7 × 105Which of the following [H+] values describes the most basic (alkaline) solution?(Points: 3) 101 M 107 M 1012 M 1014 MLemon juice is a weak acid. It has a [H+] of 5.0 × 102 M. What is the pH of lemon juice? Use a scientific calculator.(Points: 3) 1.0 1.3 1.0 2.5Pyridine is a weak base with the formula C5H5N. Pyridine reacts with water according to the following equation: C5H5N + H2O C5H5NH+ + OH. What is the formula for the dissociation constant for this base?(Points: 3) Kb = [H+][CO2H]/[C5H5N] Kb = [C5H5N]/[OH][CO2H] Kb = [C5H5N][CO2H]/[OH] Kb = [OH][C5H5NH+]/[C5H5N]
