(6pts) Calculate the oxidation states of each atom (show calculations) and identify the atom oxidized, the atom reduced, the oxidizing agent, and the reducing agent. \[ 2 \mathrm{~K}_{2} \mathrm{Cr}_{2} \mathrm{O}_{7}+2 \mathrm{H}_{2} \mathrm{O}+3 \mathrm{~S} \square 3 \mathrm{SO}_{2}+4 \mathrm{KOH}+2 \mathrm{Cr}_{2} \mathrm{O}_{3} \] 14. (6pts) what volume of \( 0.194 \mathrm{M} \) potassium chloride solution is required to react exactly with \( 50.0 \mathrm{~mL} \) of \( 0.230 \mathrm{M} \) lead (II) Nitrate? Hint: write equation
