2. There is a need to make many 10mm holes in a rubber hose. It is not hard to punch or drill holes except that the hose is very flexible. It stretches, compresses and bends. So, making the holes accurately is a complicated task. The supervisor tried to burn the holes with a heated iron rod, but the edges of these holes were uneven and brittle. "Nothing can be done! How annoying!" exclaimed the exasperated supervisor. How could it be done?

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…

Although the actual process also requires water, a simplified equation (with rust shown as Fe,O3) is: points References 4 Fe(s) + 3 O2(g)→2 Fe,O3(s) AH =-1.65 × 103 kJ (a) What is the AH when 0.250 kg of iron rusts? x 10 kJ (b) How much rust forms when 9.40 x 10° kJ of heat is released? x 10 g Fe,O3
