To view and manipulate the molecules in this exercise using Jmol, it is necessary to use a web browser that supports Java applets. In addition, some web pages using the Jmol applet include HTML controls (buttons, checkboxes, etc.) that send scripts to control the Jmol applet. In order for these controls to function properly the web browser must also support JavaScript and LiveConnect communications between JavaScript and Java applets. (This is not the case for this exercise.)

The above linked molecular images are of naturally occuring or man-made gases. They must be manipulated in order to get a correct view of the molecules. Complete the table for the molecular images: 1) write a molecular formula for each, 2) name each of the molecules, 3) provide the molar mass and estimate whether the gas is more dense, less dense or about the same density as air, and 4) identify each gas as being either a "natural" component of the atmosphere or as a molecule predominately introduced into the atmosphere by human (anthropogenic) activity. For example, 4A: SO₂, sulfur dioxide, 64 g/mol, likely more dense than air, anthropogenic: introduced mainly by industrial smokestack operations.
 

The following image is of a microbe named Methanosarcina. It has an interesting relationship to greeenhouse gases.
