a. Step 1 in constructing a Lewis structure is to calculate the number of valance electrons available. How many valance electrons are available in the following molecular formula, HCP? (Final answers to this question must be included in the space below to receive credit) b. Step 2 in constructing a Lewis structure is to identify the central atom and draw single bonds between the central atom and all non-central atoms. Show the process and resulting intermediate Lewis structure for this step below for HCP. (This intermediate structure should be shown on your scratch paper sent to Dr. Metz) c. How many valence electrons are represented after Step 2 (part b)? How many valance electrons remain to complete the Lewis structure? (Final answers to this question must be included in the space below to receive credit) d. Step 3 in constructing a Lewis structure is to place nonbonding electron pairs around all non-central atoms to complete their octet. Show the process and resulting intermediate Lewis structure for this step below for HCP. (This intermediate structure should be shown on your scratch paper sent to Dr. Metz) e. How many valence electrons are represented after Step 3 (part c)? How many valance electrons remain to complete the Lewis structure (Final answers to this question must be included in the space below to receive credit) f. What is the electron domain geometry for HCP? (Final answers to this question must be included in the space below to receive credit) g. What is the molecular geometry for HCP? (Final answers to this question must be included in the space below to receive credit)

(05.04 MC)Based on this cladogram, which pair of organisms are likely to share the most similarities with each other?

A two-month old boy presents for his well child exam, but mom’s primary concern is his crying and fussiness throughout the day, especially in the evenings. His mother is convinced it is his milk-based formula (Similac Advance) which he has been on for the past 3 weeks as he has weaned off breast milk. Everything else on history & a complete exam is within normal limits. Answer the next two (2) questions based on this case. If the new formula for the baby doesn’t make any difference in his symptoms, your next step is:

To plan a life test, keeping all other planning parameters constant, if the allowed number of failures is reduced from 2 to 1, then the testing duration can be
