Use the following information to answer numerical-response question 10. Crude oil is separated into different groups of hydrocarbons, or fractions, in a fractional distillation tower. Two different locations at which fractions can be removed from the tower are labelled in the diagram below. Numerical Response Fractional Distillation Tower Crude oil K-11090 the greatest amount of CH4(g) is numbered the largest molecules is numbered molecules with the highest boiling points is numbered 10. Match the numbers of the locations in the diagram above with the descriptions of the fractions that could be removed as given below. The location with the fraction that contains molecules that are least attracted to one another due to weak intermolecular forces is numbered Location 1 190071 Location 2 zonirabi woll (Record in the first column) (Record in the second column) (Record in the third column) (Record your answer in the numerical-response section on the answer sheet.)

Concentration of Reagents (NH4)2S2O8 KI Na2S2O3 0.25 M 0.22 M 0.19 M Volumes of Solutions S₂082 (mL) Starch soln (mL) KNO3 (mL) EDTA soln (mL) KI (mL) S₂O32- (mL) x 5 9.7 0.9 26.4 0.5 9.9 1.1 Using the above data determine the concentration of I at the moment the reaction begins. HINT: This is a mixing problem. Determine the total number of moles of I and divide this amount by the total volume (in L). Be careful... If you go back and try this exercise again the values will change. Read the question carefully! Answer:
