5. Why are most metals polycrystalline in microstructure. How would you get a: a. large grained metal b. fine grained metal

25. It is possible to measure the way light interacts with a material. In one lab we looked at how much light is transmitted through a colored solution. Since different wavelengths of light have diferent energies, we can interpret some of the energies involved in these compounds. a) What is the "opposite" of percent transmission (%T)? b) What does the visible spectrum of a material, especially that from a complex compound of a transition metal, tell us about the material? c) Describe a way to measure the spectrum of a solution. d) Is it possible to use the spectra of different materials to identify them? How?

If a strip of magnesium ribbon is ignited in a Bunsen burner flame, the magnesium burns brightly and produces a quantity of white magnesium oxide powder. 1S From the information given above, indicate one chemical property of magnesium metal. O Magnesium is able to be pounded and stretched into long, thin, narrow "ribbons". O Magnesium is malleable. O Magnesium burns in air. O Magnesium "ribbons" are often used in the introductory chemistry lab as a source of the metal.
