Here's a problem for you to solve:What is the enthalpy change (∆H) for the combustion of methane (CH4) to form carbon dioxide (CO2) and water (H2O) based on the following information?CH4(g) + 2O2(g) -> CO2(g) + 2H2O(l) ∆H = -890.4 kJ/molYou have a sample of methane and you want to determine the heat released or absorbed during combustion. How much heat is produced when you burn 5.00 grams of methane (CH4) at a constant pressure of 1 atm, assuming that the products are carbon dioxide (CO2) and water (H2O) and that the heat capacity of the calorimeter is negligible?

Determine the standard enthalpy of formation of methane (CH4) given the following information: The standard enthalpy of formation of CO2 and H2O are -393.5 kJ/mol and -285.8 kJ/mol, respectively. The combustion of 0.50 g of methane in a bomb calorimeter resulted in a 1.20°C temperature increase of the surrounding water. The heat capacity of the bomb calorimeter is 5.85 kJ/°C.

Determine the standard enthalpy of formation for hydrogen chloride gas using the following data:H2(g) + Cl2(g) → 2HCl(g) ΔH = -184.6 kJ/molH2(g) + 1/2O2(g) → H2O(l) ΔH = -285.8 kJ/mol2HCl(g) + O2(g) → 2ClO(g) + H2O(l) ΔH = -518.2 kJ/mol Note: The standard enthalpy of formation for a compound is the change in enthalpy that occurs when one mole of the compound is formed from its constituent elements, with all substances in their standard state at a given temperature (usually 25°C) and pressure (usually 1 atm).
