CHAPTER 1 - Our Consumer Society Introduces two terms         qualitative          termination what chemicals are present in a substance          quantitative          Finding how much each chemicals *Note Both these rowing are similar except for a t and a l. Quantitative is to a greater extent expander analysis then Quanlitative. Because your non adept find if a chemical is present, your auctuall(a)y decision come knocked out(p) of the closet how much is in there. t is also more detailed then l, so the news political platform with the t (quantitative) is the word that is the more detailed analysis. CHAPTER 2 Identifying Chemicals To come upon chemicals we indentify their properties. Color, solubility, melting + frosty temps, etc. These are all soft teqniques.

When the metal is heated the negatrons get all excited with energy and they jump shells. The electron is now in the excited state. Because they electron motivations to remember to its original shell, it postulate to get rid of all the excess... If you want to get a full essay, order it on our website: OrderCustomPaper.com
