Answer the fоllоwing questiоn. Use the properties of enthаlpy аs а state function (version of Hess's law) and data below to calculate the enthalpy change for the given reaction (Hint: Do not forget about the coefficients) Standard Enthalpy of Formations in kJ/mol at 298.15 K ΔHof ΔHof AlCl3(s) -704.2.0 Al2O3(s) -1676 H2O(l) -285.8 H2O(g) -241.8 NH4ClO3(s) -265.2 N2O(g) 81.6 Use the properties of enthalpy as a state function (version of Hess's law) and data above to calculate the enthalpy change for the reaction (Hint: Do not forget about the coefficients): 6Al(s) + 6NH4ClO3(s) => 2Al2O3(s) + 2AlCl3(s) + 3 N2(g) + 12H2O(g) ΔH = ?
