Use the information in the ALEKS Data tab to sort the following chemical species by oxidizing power. Write a balanced half-reaction for the oxidation of aqueous hydrogen peroxide \( \left(\mathrm{H}_{2} \mathrm{O}_{2}\right) \) to gaseous oxygen \( \left(\mathrm{O}_{2}\right) \) in basic aqueous solution. Be sure to add physical state symbols where appropriate. Caiculate the \( \mathrm{pH} \) at \( 25^{-\circ} \mathrm{C} \) of a \( 0.61 \mathrm{M} \) solution of trimethylammonium chloride \( \left(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{NHCl}\right) \). Note that trimethylamine \( \left(\left(\mathrm{CH}_{3}\right)_{3} \mathrm{~N}\right) \) is a weak base with a \( p K_{b} \) of \( 4.19 \) Round your answer to l decimal place. Using standard reduction potentials from the ALEKS Data tab, calculate the standard reaction free energy \( \Delta G^{0} \) for the following redox reaction. Round your answer to 4 significant digits. \[ 2 \mathrm{Mn}^{2+}(a q)+8 \mathrm{H}_{2} \mathrm{O}(l)+5 \mathrm{Zn}^{2+}(a q) \rightarrow 2 \mathrm{MnO}_{4}^{-}(a q)+16 \mathrm{H}^{+}(a q)+5 \mathrm{Zn}(s) \] For 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 \( S \) of the system, decrease \( S \), or leave \( S \) unchanged, If you don't have enough information to decide, check the "not enough information" button in the last column. A chemistry graduate student is given 125. \( \mathrm{mL} \) of a \( 1.00 \mathrm{M} \) pyridine \( \left(\mathrm{C}_{5} \mathrm{H}_{5} \mathrm{~N}\right) \) solution. Pyridine is a weak base with \( K_{b}=1.7 \times 10 \). What mass of \( \mathrm{C}_{5} \mathrm{H}_{5} \mathrm{NHBr} \) should the student dissolve in the \( \mathrm{C}_{5} \mathrm{H}_{5} \mathrm{~N} \) solution to turn it into a buffer with \( \mathrm{pH}=4.96 \) ? You may assume that the volume of the solution doesn't change when the \( \mathrm{C}_{5} \mathrm{H}_{5} \mathrm{NHBr} \) is dissolved in it. Be sure your answer has a unit symbol, and round it 2 significant digits.
