Calculate the standard enthalpy of formation of hydrogen fluoride (HF) given the following reactions and enthalpy change values:2H2(g) + O2(g) → 2H2O(g) ΔH° = -484 kJH2(g) + Cl2(g) → 2HCl(g) ΔH° = -184 kJ1/2 F2(g) + H2(g) → HF(g) ΔH° = -273 kJ.

Calculate the enthalpy change for the hydrolysis of sucrose given the following information: Sucrose (C12H22O11) reacts with water to form glucose (C6H12O6) and fructose (C6H12O6). Delta H for the reaction is -190 kJ/mol. The enthalpy of formation for sucrose is -2227 kJ/mol, the enthalpy of formation for glucose is -1274 kJ/mol, and the enthalpy of formation for fructose is -1266 kJ/mol.
