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…

The pencil's "lead" main element is: a. C b. Sn c. Ld d. Pb I need explanation in a research way. Please don't base the answer to any articles that can be seen in google instead base it with a research paper or any studies with authors. Book-supported is also okay.
A concentration of carbon monoxide of 4000 ppm (0.400 % by mass) in air is lethal in about half an hour. What mass in grams of carbon monoxide in a car with an internal volume of 2.9 m3 is sufficient to provide that concentration? Assume the density of air is 1.29 g/L ; 1m3=1000L.

Souring of wine occurs when ethanol is converted to acetic acid by oxygen: C2H5OH(l) +O2(g)--->CH3COOH(g)+H2O(l). A 1.00 L bottle of wine labeled as 7.00% (%v/v) ethanol, is found to have a defective seal. Analysis of 1.00 mL showed that there were 0.0274 g acetic acid in that 1.00 mL. The density of ethanol is 0.816 g/mL. (a) What mass of oxygen must leaked into the bottle in pounds(lb) (b) What is the percent yield for the conversion of ethanol to acetic acid, if oxygen is in excess
