(6pts) Newman Projections From the procedure 1. Build a model of 2,2,5,5-tetramethylhexane. 2. Orient the model so that you are looking at the carbon with the arrow pointing to it in Figure 3. Align the bond to the next carbon in the chain so that it is directly behind the first carbon to match a Newman projection view. (See Figure MM.3 in the lab manual) 3. Spin the carbons on either side of the bond you're looking down to cycle through all three staggered and all three eclipsed positions of the substituents. 4. Draw all six positions as Newman projections on the data sheet and identify the position with the highest energy. (6pts) Draw the six Newman projections of all of the different energy levels. Label each as staggered or eclipsed and rank in order from lowest energy to highest. TA $$X$$ $$X^2$$ $$\Omega$$ $$\Sigma$$

11. Referring to the illustrations and text of Life Before Birth: Normal Fetal Development, answer the following: Which two organ systems are extensively developed in the very young embryo? and Describe the direction of development by circling the correct descriptions below: proximal-distal distal-proximal caudal-rostral rostral-caudal Does body control during infancy develop in the same directions? Think! Can an infant pick up a common pin (pincer grasp) or wave his arms earlier? Is arm-hand or leg-foot control achieved earlier? 12. Note whether each of the following organs or organ systems develops from the (a) ectoderm, (b) endoderm, or (c) mesoderm. 1. skeletal muscle 4. respiratory mucosa 7. nervous system 2. skeleton 5. circulatory system 8. serous membrane 3. lining of the GI tract 6. epidermis of skin 9. liver, pancreas

A chemist fills a reaction vessel with 4.23 atm chlorine ($Cl_2$) gas, 9.47 atm phosphorus ($P_4$) gas, and 2.78 atm phosphorus trichloride ($PCl_3$) gas at a temperature of 25.0°C. Under these conditions, calculate the reaction free energy $\Delta G$ for the following chemical reaction: $6Cl_2(g) + P_4(g) \rightarrow 4PCl_3(g)$ Use the thermodynamic information in the ALEKS Data tab. Round your answer to the nearest kilojoule
