Calculate the enthalpy change for the combustion of 1 mole of methane (CH4) gas given that the standard enthalpy of formation of methane is -74.8 kJ/mol, and the standard enthalpies of formation for carbon dioxide (CO2) and water (H2O) are -393.5 kJ/mol and -241.8 kJ/mol respectively. The balanced chemical equation for the reaction is:CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (l)

A student wants to know how the equilibrium position of a weak acid such as acetic acid would be affected if they add more acetate ion. If the initial concentration of acetic acid is 0.1 M and initial concentration of acetate ion is 0.05 M. What will be the new concentration of acetate ion necessary to increase the pH of the solution by 0.5 units?

A chemistry student wants to calculate the enthalpy of adsorption for the adsorption of nitrogen gas on a solid adsorbent. The student knows that the initial and final pressures of the nitrogen gas are 1 bar and 0.5 bar, respectively, and the surface area of the adsorbent is 2m^2/g. The student also has data on the temperature and the amount of nitrogen gas adsorbed on the adsorbent. Can you help the student calculate the enthalpy of adsorption?
