Q1. A scientist measures the standard enthalpy change for the following rxn to be 96.1KJ: NH4Cl(aq) = NH3(g) + HCl(aq). Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of NH4Cl(aq) is ----

Q2. The standard enthalpy change of combustion [ to CO2(g) and H2O(l)] at 25 degree celcius of the organic solid 1-naphthoic acid, C11H8O2(s), is determined to be -5120.6KJ/mol. What is the dH of formation C11H8O2(s) based on this value? Use the following data: DH of formation H20(l) = -285.83KJ/mol, DH of formation CO2(g) = -393.51KJ/mol.

Show work please. Need it ASAP thanks.
