IB Chemistry: Bond enthalpy questions

Use the values of bond enthalpies given in Section 11 of the IB Chemistry data booklet.1. All hydrocarbons burn according to the following equation (the state of the hydrocarbon, CxHy, at standard conditions varies according to its mass and structure):CxHy + (x + ¼y)O2(g) → xCO2(g) + ½yH2O(l)Explain, in terms of bond enthalpies, why the combustion of all hydrocarbons is exothermic.2. Nitrogen and hydrogen react to...
