Solved For the acid-base equilibrium: HNO2 + H2O + NO2 + | Chegg.com
SOLVED: The equilibrium constant Ka for the reaction Co(H2O)6^3+ (aq) + H2O (l) —> Co(H2O)5(OH)2+ (aq) + H3O+ (aq) is 1.0x10^-5 A) Calculate the pH of a 0.16 M solution of Co(H2O)6^3+.
54. If H2 + 1/2 02- >H20, AH=- 68.39 kcal K + H2O → KOH (aq) + 1/2 H2, AH=- 48 kcal KOH + water ->KOH (aq), AH=- 14 kcal The heat of formation of KOH is (A) - 68.39 +48 – 14 (B) - 68.39 – 48 + 14 (C) 68.39 – 48 + 14 (D) + 68.39 +48 – 14
