A chemistry student wants to understand the effect of changing the volume on the equilibrium position of a chemical reaction. Accordingly, the student designs an experiment where they mix 0.2 mol of nitrogen gas with 0.1 mol of hydrogen gas in a 1 L container and allow them to react to form ammonia gas. If the reaction reaches equilibrium at a certain temperature and the volume of the container is suddenly decreased to 0.5 L, what will be the effect on the concentration of ammonia gas?

A chemistry student wants to calculate the enthalpy change (∆H) upon hydrolysis of magnesium chloride (MgCl2). The student knows that the enthalpy of formation (∆Hf) of MgCl2 is -641 kJ/mol and the enthalpy of formation of water (∆Hf) is -286 kJ/mol. The balanced chemical equation for the hydrolysis of magnesium chloride is MgCl2 + 2H2O → Mg(OH)2 + 2HCl. Calculate the enthalpy change (∆H) of this reaction.
