Use the table below to answer the following question: Substance Bond Type Density Water Polar covalent 1.0 g/mL Oil Nonpolar covalent 0.91 g/mL Chloroform Polar covalent 1.49 g/mL Ammonia Polar covalent 0.73 g/mL Gasoline Nonpolar covalent 0.70 g/mL Polyethylene Nonpolar covalent 0.98 g/mL An unknown substance dissolves in water but separates and floats in oil. What is the identity of the unknown substance and why? O A. Chloroform because polar substances dissolve in water and the density must be greater than 0.91 g/mL for it to float in the oil. O B. Ammonia because polar substances dissolve in water and the density must be less than 0.91 g/mL for it to float in the oil. O C. Gasoline because nonpolar substances dissolve in water and the density must be less than 0.91 g/mL for it to float in the oil. O D. Polyethylene because nonpolar substances dissolve in water and the density must be greater than 0.91 g/mL for it to float in the oil.

An unknown substance dissolves in water but separates and floats in oil. What is the identity of the unknown substance and why?
O A. Chloroform because polar substances dissolve in water and the density must be greater than 0.91 g/mL for it to float in the oil.
O B. Ammonia because polar substances dissolve in water and the density must be less than 0.91 g/mL for it to float in the oil.
O C. Gasoline because nonpolar substances dissolve in water and the density must be less than 0.91 g/mL for it to float in the oil.
D. Polyethylene because nonpolar substances dissolve in water and the density must be greater than 0.91 g/mL for it to float in the
oil.
