- It will sink in water.
- It is non-toxic.
Show hintHide hint
Think about the relationship between phase and pressure.
4Question 4.

- True
- False
Show hintHide hint
Consider how chemicals interact in various environments.
Question 5.
A chemical with a vapor pressure of 50 mmHg spills into soil with a high organic content. Discuss its likely distribution in the soil and air.
Show hintHide hint
Consider both adsorptive behavior and evaporation.
Question 6.
Analyze the partition constants of two chemicals, one with high water solubility and low vapor pressure, and another with low solubility and high vapor pressure. Predict their environmental fate.
Show hintHide hint
Reflect on how phase behavior impacts distribution.
