Question type: Shopping & Pricing. I'm looking at buying a 2011 BMW 335 Manufacturer buyback that was originally from California. I've gotten over the stigma of buying a buyback,' since the car has been repaired by BMW, is still under warranty and the price is a lot closer to what I'm willing to spend. The reason it was bought back was for an extended crank issue, which has been completely resolved.
Do you think we can use the flame test to determine the identity of unknown in a mixture? Why or why not? I think that the flame test could be used to determine the identity of unknowns in a mixture, however it would not be very effective. This is because if there are to many different compounds, or elements, all of the colors of light mixed together would bring the flame closer to just emitting white light.
  Answer   When a metallic ion is heated in a flame test, the heat (energy) causes an electron to be exicted to a higher energy state. When this electron returns to a â¦ lower energy state, energy is emitted as visible light.nswer by M769670296706206. Confidence votes 93. When an electron jumps from an energy level that is farther away from the nucleus to an energy level that is closer to the nucleus the electron gives off energy. When doing a flame test this energy is in the form of a color change.
