Gas Law Internet Activity Conclusion

The phet gas simulation represented a chamber that you were exerting molecules into, whether it was heavy or light. Then you pumped the air out and the pressure and number of molecules would rise with each pump. The "heavy species" were larger molecules, than the "light species". After going through the procedure with each type of molecule I started making comparisons. I noticed that in the lighter species it took more molecules to get around the same pressure. The smaller molecules were also moving much faster, than the larger molecules. This is because it takes more energy for the larger molecule to move. With each pump less large molecules were exerted, than light molecules. This is again because it takes more of the smaller molecules to increase the pressure in the chamber.

Chemistry in Action!

Question 1:
What type of reaction is 1a? Double Replacement
What type of reaction is 1b? Corrosion
What do you think reaction 2 and 3 are? Double Replacement, Neutralization, Single Replacement


Question 2:
What is hypoxia? family of conditions characterized by a lack of oxygen in the body's tissues


When does hypoxia reach its highest levels in Long Island Sound and the Gulf of Mexico? Hypoxia reaches its highest levels in the long island sound and in the Gulf of Mexico when high levels oh phytoplankton are present.


What are the causes of hypoxia? Pollution and eutrophication in which plant nutrients enter a river, lake, or ocean, and phytoplankton blooms are reproductive, occur in the absence of pollutants.


Research the sources of high levels of nitrate ion in water bodies. Some sources of high levels of nitrate ion in water bodies are natural runoffs and septic waste. 


What are "safe levels" of nitrate in drinking water and what are the effects on humans of drinking water with high levels of nitrate ion? The “safe level” of nitrate in drinking water is 10 mg of nitrate per liter of water. The effects on humans of drinking water with high levels of nitrate ions are methemoglobinemia or blue baby syndrome. Blue baby syndrome is an illness that arises when an infant’s blood is unable to carry enough oxygen to body cells and tissue.
