1. The general public often expects solutions to our environmental issues that have zero risk. Explain in less than 200 words whether this is possible, supporting your answer with a thoughtful discussion of what risk is and how to calculate risk.

2. Name two different chemicals we have covered in the course content that we have added to the carbon cycle that did not exist naturally. Please reference the source from our required readings.

a. Which functional group does each chemical belong to? Explain.

b. How does the type of bonding and functional group these molecules posses affect their reactivity?

c. What are the health and environmental effects of the two chemicals you choose to report on? Make sure to obtain your information from reliable sources and reference relevant sources.

d. Take one of the chemicals you choose to discuss and explain the properties of that chemical (such as water solubility, vapor pressure, etc.) that determines its migration in our environment.

e. Name one green chemistry principle that could have the greatest potential to minimize the future impact of each of the two chemicals you discussed, explaining how each green chemistry principle can be applied specifically to each chemical.
