QuestionFor each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy SS of the system, decrease SS, or leave SS unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. Note for advanced students: you may assume ideal gas and ideal solution behaviour. \begin{tabular}{|c|c|c|} \hline System & Change & ΔS\Delta S \\ \hline A solution made of sodium iodide (NaI) in water, at 27C27^{\circ} \mathrm{C}. & 50. mL of pure water is added to the solution. & ΔS<0\Delta S<0 ΔS=0\Delta S=0 ΔS>0\Delta S>0 not enough information \\ \hline A 0.35M0.35 M solution of sucrose in water, and a beaker of pure water, both at 37.C37 .{ }^{\circ} \mathrm{C}. & The solution is put into a semipermeable bag immersed in the water, and 50.mL50 . \mathrm{mL} of pure water flows through the bag into the sucrose solution. & ΔS<0\Delta S<0 ΔS=0\Delta S=0 ΔS>0\Delta S>0 not enough information \\ \hline 20. L of pure argon (Ar) gas and 20.0 L of pure carbon dioxide (C12)\left(C_{12}\right) gas, both at 3 atm and 15C15^{\circ} \mathrm{C}. & The gases are mixed, with the pressure kept constant at 3 atm . & ΔS<0\Delta S<0 ΔS=0\Delta S=0 ΔS>0\Delta S>0 not enough information \\ \hline \end{tabular}

Studdy Solution
For the sodium iodide solution: ΔS>0\Delta S > 0. For the sucrose solution: ΔS>0\Delta S > 0. For the argon and carbon dioxide gases: ΔS>0\Delta S > 0.
