a) A certain amount of Pennsylvania coal, in a final analysis
(by mass), has 84.36% C, 89% H2, 4.40% O2, 0.63% N2, 0.89% S and
7.83% ash (non-combustible). This coal is burned with a theoretical
amount of air. Disregarding the ash content, determine the molar
fractions of the products.

For reasons we will discuss in class, it turns out that a way we can calculate the enthalpy change for a reaction is by summing up all the heats of formation of the products and subtracting out the sum of the heats of formation of the reactants: ΔΗn-Σ ηΔΗproducts -ΣnΔΗ'f reactants rxn Use this method to calculate the standard enthalpy...
