Determine the enthalpy change of precipitation for the reaction between 50ml of 0.1M sodium sulfate and 50ml of 0.1M barium nitrate, given that the final temperature is 25°C and the initial temperature was 30°C. The specific heat capacity of the solution is 4.18 J/g °C and the density is 1 g/mL. (Assume the reaction goes to completion and all volumes are additive.)

A student wants to know the equilibrium concentration of hydrogen gas and nitrogen gas at a particular temperature and pressure when they are mixed in a container in a 2:1 ratio. The student also wants to calculate the equilibrium constant of the reaction when nitrogen and hydrogen form ammonia. Can you help the student by designing a step-by-step procedure to find the equilibrium concentrations and equilibrium constant at the given conditions?
