Determine the standard enthalpy change of the reaction between 50.0 mL of 0.200 M hydrochloric acid (HCl) and 50.0 mL of 0.100 M sodium hydroxide (NaOH) at 25°C. The reaction is a neutralization reaction between HCl and NaOH, and the products are water and sodium chloride (NaCl). The molar enthalpy of formation of NaCl is -411.2 kJ/mol, and the specific heat capacity of the aqueous solution is 4.18 J/g°C.

A chemistry student needs to determine the new equilibrium concentration of a complex ion, if the temperature is increased by 10°C from the initial temperature of 25°C, and the equilibrium constant for the reaction is 0.056. The initial concentration of the reactants are: [Fe3+] = 0.025 M, [SCN-] = 0.015 M, and [FeSCN2+] = 0.007 M.
