1. Hydrocarbons and their derivatives are organic compounds that contain carbon and hydrogen, and they easily undergo combustion in air to produce carbon dioxide and water. Octanol (C8H17OH) is an organic alcohol, which is a derivative of the eight carbon hydrocarbon octane. When burned in air, octanol has an enthalpy of combustion of - 5294 kJ. Based on the information provided, write the balanced thermochemical equation for the combustion of octanol.
Also if you could, please explain how you developed the equation, and specify what the equation tells us about the reaction?
2. Nitrogen gas can be combined with oxygen gas to form nitrogen dioxide gas (NO2). Using this information and the reactions below, determine the overall enthalpy for this reaction using Hess's Law.
N2 (g) + 3H2 (g) → 2NH3 (g) ΔH = -112.3 kJ
2 NH3 (g) + 4 H2O (l) → 2 NO2 (g) + 7 H2 (g) ΔH = -144.9 kJ
H2O (l) → H2 (g) + ½ O2 (g) ΔH = -48.0 kJ
