The bond angle about angle a is: [blank1] degrees b.  The bond angle about angle b is: [blank2] degrees c.  The electron domain geometry of atom c is: [blank4] d.  The molecular geometry of atom c is: [blank5] e.  The hybridization of atom d is: [blank3]

(WCSP25) We often use theory (valence bond, hybridization, resonance, etc.) to explain experimental data. The molecule below is experimentally determined to have bond angles of exactly 120 degrees.    Based on this information, answer the following questions: a. What is the molecular geometry about the central carbon atom? [blank1] b. What is the hybridization of the central carbon atom? [blank2] c. What type of orbital holds the unpaired electron? [blank3]

Read the following passage from “The Yellow Wallpaper” and answer the question that follows: “There are things in that paper that nobody knows but me, or ever will.”   Question: Identify and explain the significance of two literary devices used in this line. Consider elements like dramatic irony, foreshadowing, or symbolism. How do these devices contribute to the story’s development? (10 points)
