Discuss the properties of Perfluorinated Chemicals (PFCs) that influence their transport in the subsurface among the solid, liquid and vapor phases
Homework Answers
PFC's are molecules made up of Carbon atoms to which fluorine atoms are attached.
Because of the strength of C-F bond molecules are highly stable and resistant to any kind of degradation.
These compounds may undergoes biomagnification and is detected in both liquid and solid phase in most samples. These are unique as they repel oil, grease and water. Thus, they have been used to make surfactants.
Because of such properties PFC's influence their transport in subsurface among solids, liquids and gases phase.
Hope this helps you

Magnetic properties (diamagnetic or paramagnetic behavior) of different chemicals are predicted b... Magnetic properties (diamagnetic or paramagnetic behavior) of different chemicals are predicted based on the absence of presence of unpaired electrons. For diatomic covalent species, the MO theory should be used. For polyatomic molecules and molecular ions, Lewis structures should be used. For atomic ions and ionic solids that include them, electronic configurations should be used. Label each of the following species as diamagnetic or paramagnetic and indicate if...

Describe the stretch-shortening cycle (SSC). Then discuss how the elastic properties of muscle and the Series Elastic Components (SEC) relate to each other. How do proprioceptors facilitate the speed at which plyometrics are accomplished, and specifically, the SSC? Finally, what is the goal of plyometric training with respect to changing the duration of phases within the SSC?

C1. Water Water has a number of unique properties that are essential for life. Most of these properties are as a result of the polar nature of water and its ability to form hydrogen bonds. Using your knowledge on the properties of water, answer the questions below. a) Why is it important for water to be a liquid over a broad range of temperatures? [2 marks] b) Why is water referred to as polar and why does its polarity affect...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
