So a Flame Test Investigation was conducted. In that activity, short wooden splints (sticks)were soaked in eight different chemical solutions. The splints were then held over a lit Bunsen burner oneat a time, at which time each one gave off a distinctive color of light Each splint produced a dominant, vibrant color, and the color was different for each one. Forexample, the splint soaked in copper chloride produced a green flame and the splint soaked in lithiumchloride produced a brilliant red flame. Please explain the following for me: 1. Why do chemicals give off light when heated by a Bunsen burner? 2. None of the chemicals produced “white light” similar to a common light fixture. In otherwords, none of the chemicals gave off the entire spectrum of visible colors. Why not? 3.  Why does each chemical give off its own unique color that is different from every otherchemical?   Give thorough explanations. Also, when explaining, correctly use each of the following terms at least…

Potentially Useful Information Spectrochemical Series: I < Br° < SCN" < cI' < NO3° < F° < OH° < C2O4²- ~ H2O < NCS“ < NH3 < en < PPH3 A student has three test tubes containing a metal (M) nitrate solution M(N03)2 (aq) (where "M" represents a generic transition metal). The student adds aqueous ammonia (NH3) to one test tube, aqueous hydrochloric acid (HCI) to the second tube, and nothing more to the third tube, but forgets to label the tubes. After this, one test tube contains a red solution, one an orange solution, and one a yellow solution. Note: This metal, M, would follow the same rules that we used for Cu(II), Ni(II), and Co(II). The Jahn-Teller Effect does not apply. Complete each statement or answer each question below about the solutions in the three test tubes. The yellow solution contains a coordination complex with... water (H2O) as the ligand. nitrate ion (NO3') as the ligand. chloride ion (Ci") as the ligand. O ammonia (NH3) as the ligand.
