Calculate the standard enthalpy change (∆H°) for the reaction of the coordination compound [Co(NH3)6]Cl3 (aq) with NaOH (aq) to produce [Co(NH3)6](OH)3 (aq) and NaCl (aq). Given, the standard enthalpy of formation (∆H°f) for [Co(NH3)6]Cl3, [Co(NH3)6](OH)3 and NaCl are -784.8 kJ/mol, -1273.6 kJ/mol and -411.2 kJ/mol, respectively.

A student wants to analyze the composition of a sample of an unknown metal alloy. They dissolve a 0.500g sample of the alloy in hydrochloric acid to form a solution which is then titrated with sodium hydroxide (NaOH) to neutralize the acid. The volume of the NaOH solution required is 16.50 mL. Assuming the acid reacts with the metal in the alloy according to the formula: M + 2HCl → MCl₂ + H₂, what is the percent composition by mass of Metal M in the alloy?

A chemistry student wants to determine the effect of adding more reactant or product on the equilibrium position of a chemical reaction. The student has a 0.50 M solution of N2O4 and NO2 at equilibrium at 25°C, with the equation N2O4(g) <--> 2NO2(g). If the student adds more N2O4 to the reaction mixture, what will happen to the equilibrium concentration of NO2? Will it increase, decrease or stay the same? Justify your answer with a chemical equation and relevant calculations.
