Can someone do several chemistry assignments for me?

ChemActivity #2

Instrumental Analysis

Model:

Instrumental analysis is the use of sensitive machines or instruments to obtain information about a chemical. Many instruments use a type of light to pass through a chemical. The interaction of a specific wavelength of light with a chemical can tell us what type of chemical it is, and in some cases the exact structure of a molecule. The use of light is called spectroscopy since light waves are part of the electromagnetic spectrum.

Table 1. The electromagnetic spectrum and how certain wavelengths of light affect chemicals.

Critical Thinking Questions:

1. Which type of light has the highest energy?

2. Which type of light has the shortest wavelength?

3. Which type of light has the lowest energy?

4. Which type of light has the longest wavelength?

5. Which type of light causes the most damage to a chemical, and hence human cells?

6. What type of spectroscopy was used to determine the elemental composition of Chigger’s cremains in the case study?

7. What are two other types of instrumental techniques have you encountered in reading the chapters?

8. Which method is best for visualizing an element or molecule?

9. Which method is best for detecting the isotopes of elements?
