List the electron geometry and molecular geometry of the following compounds/ions.  If the molecule/ion has a resonance structure, draw the second resonance structure.   If the molecule/ion does not have a resonance structure, do not draw the second one as it doesn’t exist. You need to draw them out on a paper and upload your results.  You can use your phone to take a picture of your answer and upload them. a) O3b) PF5c) HCO2-;  C is the central atomd) SiCl4e)  ClO3-f) HCN

How many subsets does the following set have? T = {t, e, a, c, h, k, i, d, s}  Express answer as a Natural Number 

A guidance counselor asked 60 adults whether they had studied certain subjects in school. He found that: 15 studied Algebra (A) and Biology (B) 2 studied only Biology 17 studied Algebra and Chemistry  (C) 35 studied Chemistry 18 studied Chemistry and Biology 8 studied none of these 12 studied all three subjects Remember: A = Algebra B = Biology C = Chemistry Draw and complete the Venn Diagram on your paper. Fill in the number of students for each of the numbered areas (labeled in red)  Area 1 [1]                    Area 2 [2] Area 3 [3]                    Area 4 [4] Area 5 [5]                    Area 6 [6] Area 7 [7]                    Area 8 [8]

Given:  B x A = Be sure to write your answers using proper notation – using ( ) and/or  { } correctly – as needed. a.  Set A = [a] b.  Set B = [b] c.  (B x A) = [c]

Brad did a study of whether any of the African national flags contained the colors red or blue. Of the 53 flags he studied, 8 had neither red nor blue, 13 have both red and blue, and 38 had red.  HINT:  Draw a Venn Diagram to help solve the problem. a.  How many flags had contained the color blue? [a] b. How many flags contained the color red, but not blue?  [b]

In the box below, list all the subsets of the set  G= {g, e, m} Be sure to write your answer using proper notation.

Choose   YES or  NO   from the Dropdown Menu. Given      U = {p, u , b, l, i, s, h, e, d}  and    A = {b, u, i, l, d}             B = {s, h, i, p}          C = {s, h, i, e, l, d}      D = {d, e, l, i, s, h}     E= {s, h, e, d} a. Is D = C ?   [a] b. Is E ⊄ C ?  [b] c. Is {u} ∈ A ?  [c]  d. Is B ~ E ?  [d]  e. Is D ⊆ E ?  [e]  f. Is p ∈ D ?  [f]  g. Is E ⊂ D ?  [g]  h. Is C ⊆ D ?  [h]
