Dangerous Paint Stripper Jessica has a summer job working for the city parks program. She has been using a cleaner called “Graffiti Gone” to remove graffiti from the bathrooms. She has to take a lot of breaks, because the chemical makes her throat burn. It also makes her feel dizzy sometimes, especially when the bathrooms don’t have very many windows. On the label, she sees that the cleaner has methylene chloride in it. She feels like she’s managing to get the work done, but she is worried about feeling dizzy. She wants to find out more about this chemical, what harm it can cause, and whether there are safer ways to do this work. Questions for following story. 1. What went right in this situation? 2. What went wrong in this situation? 3. What steps should be taken in this workplace to make sure employees are better protected and prepared the next time?

Calculus Preface (?) Brytwave Blackboard Quizlet Clutch E Knowledge Check Question 9 Black Forest Biologicals, a biotech startup, has a promising Alzheimer's drug candidate Compound SLT-88 entering Phase I trials this year. SLT-88 is the only product formed by the reaction of two precursor compounds A and B, both of which are quite expensive. The chief medicinal chemist of Black Forest is trying out different reaction conditions to minimize the cost of manufacturing SLT-88. In the table below are listed the initial and final amounts of A and B used under two different trial conditions, and also the actual amount of SLT-88 recovered in each case. Complete the table by calculating the theoretical yield of SLT-88 and the percent yield of SLT-88. Round your amounts to the nearest milligram and your percentages to the nearest whole percent. amount of A amount of B yield of SLT-88 Trial initial final initial final theoretical actual 1000. mg 0 mg 550. mg 286. mg 999. mg 150. mg 0 mg 1000. mg…

Draw structural formulas for organic products A and B in the window below. CH3 CH3CH₂CHCHCH3 Br Li pentane A Cul B • Draw only products having the organic portion of the original alkyl halide. • Draw carbon-lithium bonds using the single bond tool. If a structure has a copper-lithium bond, do not draw the lithium. Separate products from different steps using the → sign from the drop-down menu.

Determine the structures of the missing organic molecules in the following reaction: Y II OH X + H₂O H+ H* OH Note: Molecules that share the same letter have the exact same structure.
