3. Hydrochloric acid is a strong acid that can be used to make sodium chloride and a weak acid, nitrous acid. Write the balanced chemical equation of this reaction. (You can use the information in part b to help you determine states)) b. Using the information below determine the AºHrn of the generation of nitrous acid and sodium chloride. 2NACI (s) + H;O (I) → 2HCI (aq) + Na;O(aq) AH, = 507.1 kJ/mol NO (g) + NO2 (g) → Na;O (aq) + 2NaNO; (aq) AH = -427.4 kJ/mol NO (g) + NO2 (g) → N;0 (g) + O2 (g) AHrxm =-42.8 kJ/mol 2HNO2 (aq) → N2O (g) + O2 (g) + H20 (I) AHrn = 34.2 kJ/mol %3D

Question
3. Hydrochloric acid is a strong acid that can be used to make sodium chloride and a weak acid, nitrous acid. Write the balanced chemical equation of this reaction. (You can use the information in part b to help you determine states), b. Using the information below determine the AºHrn of the gencration of nitrous acid and sodium chloride. 2NACI (s) + H;O (1) → 2HCI (aq) + Na;O (aq) AH, = 507.1 kJ/mol NO (g) + NO2 (g) → Na;O (aq) + 2NaNO; (aq) AH,n = -427.4 kJ/mol NO (g) + NO2 (g) →N20 (g) + AHrxn = -42.8 kJ/mol (8) 2HNO2 (aq) → N20 (g) + O2 (g) + H2O (I) AHrn = 34.2 kJ/mol
