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.

A student wants to know how changing the volume affects the position of the equilibrium for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g). If the reaction is initially at equilibrium in a 2 L container at 400 K and then the volume is decreased to 1 L, what will be the new concentrations of each gas at equilibrium? (Assume that the pressure remains constant and that the reaction follows the ideal gas law.)
