Assignment 9
100 points
1
Due at the start of recitation 12/3/2018, at the attention to your Recitation
Leader.
In this assignment, you will 1) review Chapters 17 and 19, and 2) practice formulating
displaying data on air quality
Part 1: Topical Review Questions
1.1)
What is the role of ozone in the stratosphere? Describe its stratospheric cycle.
How does it differ in impact from tropospheric ozone? 15 pts.
Ozone is the thick layer which is colorless, toxic and pungent smell which is
formed by oxygen through electrical discharges. The ozone acts like a blanket that
prevents ultraviolet rays from directly hitting the stratosphere hence reducing the
amount of radiation. The stratosphere circle is formed when the ozone molecule
takes in reduced ultraviolet rays making it divide into an oxygen molecule and a
free atom of oxygen, these two rejoin to form another ozone hence the ozoneoxygen cycle which affects the concentration of the ozone in the stratosphere thus
reacting easily with compounds. However, in the troposphere, it’s a little bit
different as this circle causes changes in weather conditions.
1.2)
Explain how the stability of the CFC molecule reduces stratospheric ozone. 1...
