2. Make a table that shows all the possible molecular shapes and AXE types within each of the 5 geometries: A central atom with 6 electron groups, 5 electron groups, 4 electron groups, 3 electron groups, and 2 electron groups. • For example, a central atom with 4 electron groups has a tetrahedral electron pair geometry. It includes the following molecular shapes: tetrahedral (AX4E0), trigonal pyramidal (AX3E1), and bent (AX2E2). • For a central atom with 6 electron groups, consider...

Guidelines for Drawing Lewis Structures STEP 1: Determine the total number of valence electrons for the molecule. STEP 2: Determine the skeletal structure (arrangement of atoms) of the compound. For simple compounds the singular atom will be in the center with the others arranged around it. Attach each bonded atom...

1. In a high school class of 100 students, 42 studied mathematics, 68 studied psychology, 54 studied history, 22 studied both mathematics and history, 25 studied both mathematics and psychology, 7 studied history but niether mathematics nor pychology, 10 studied all three subjects, and 8 took none of these. Randomly selecting a student from the class, what is the probability of the following event that: (a) a person enrolled in psychology takes all three subjects. (b) a person not taking...

Trigonal Planar Electron Domain Geometry (EDG) These structures all have 3 areas of e density and bond angles are approximately 120° Areas of e density include lone pairs around the central atom and peripheral atoms attached to the central atom. As the number of lone pairs increase around the central atom the bond angles are slightly decreased. Possible Molecular Geometries from this EDG are: Trigonal Planar and Bent NO3- 1) Build table to identify the # of bonds: 2) Draw...

For the following problem, use your graph class from above. In class we studied BFS. Although we discussed the algorithm, we didn't provde the code. In the graph above, the BFS will visit 2 8 4 7 6 Figure 5: A graph of order 8. all nodes if starting with 1; however, any other node will not lead to all nodes being visited. BFS actually keeps track of not only visited nodes, but unvisited. Unvisited nodes are the nodes that...
