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?

Calculate the enthalpy change of mixing 50 mL of 1 M HCl with 50 mL of 1 M NaOH at 25°C. It is known that the standard enthalpies of formation of HCl and NaOH are -92.3 kJ/mol and -469.2 kJ/mol, respectively. Assume that the heat capacity of the mixture is 4.18 J/g°C and the density of the solution is 1 g/mL.
