Consider the reaction: Cu^2+ + 4NH3 ⇌ [Cu(NH3)4]^2+ If the initial concentration of Cu^2+ is 0.5 M and the initial concentration of NH3 is 2 M, what is the concentration of [Cu(NH3)4]^2+ at equilibrium if the concentration of NH3 is increased to 5 M? (Assume the volume of the solution remains constant and the temperature is kept constant.)

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)
