Homework Answers
Yes, emission spectrum is a good way to qualitatively identify which elements are present because it examine wavelength of photons emitted by atom (from the element) during their transition from an exited energy state to a lower energy state. Each element emit a characteristic wavelength which is used to identify the element.
To determine quantitative information we will study the intensity of emitted radiation which is proportional to the number of atoms of the element.

The Great Canadian Tax Dodge It is estimated that between 100 and 170 billion dollars leaves Canada every year, untaxed. Much of it is siphoned off to Canadian-made offshore tax havens. The Great Canadian Tax Dodge documents the birth of the Canadian Tax Fairness movement and examines the issue of tax avoidance, exposing the sophisticated corporate strategies and tax loopholes commonly used to legally avoid tax. Write a review, that should be at least 500 words long. answer the following...

suppose that you have been hired by the Florida state student health services department to design a case-control study to assess the following hypothesis among Florida state students at Florida State :Irregular sleep patterns increase the risk of headaches. Be sure that your design addresses the following elements: Refine the study hypothesis so that it is as specific as possible and contains all elements of a “good” hypothesis. How will you identify and define the cases? Are there any exclusion...
