List аt leаst оne methоd yоu could use to identify whether а mystery molecule contains polar or non polar covalent bonds. List the method and explain how it would be used to determine polarity.  Hint: It is a mystery molecule so you don't know what elements it contains. That means you can't look up the properties of the mystery molecule to determine its polarity. Think about what you learned in the phenomenon activities this quarter. Come up with a simple experiment/method to determine the polarity of the mystery molecule using the information you learned in the course this quarter.
