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?

How was Thin Layer Chromatography (TLC) used in organic synthesis reactions ? TLC is used to find the exact concentration of a catalyst in the reaction. TLC can speed up a reaction because silica gel is polar. TLC can separate components of a reaction mixture such as starting materials and products allowing the experimenter to identify what compounds are in the reaction mixture. TLC is used to find percentage yield of the reaction.

Draw structural formulas for organic products A and B in the window below. -CH₂CH₂l Mg ether A CH3CO₂H, B • You do not have to consider stereochemistry. • Draw only products having the organic portion of the original alkyl halide. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate products from different steps using the → sign from the drop-down menu.

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…

Chemical companies add a chemical that gives off a distinctive odor with the gas. This is the reason we seem that rotten egg smell when it is leaking. Why is this necessary?

Please help me, there are 2 parts attached as 2 screenshots  and double and triple check your answers previous tutors have given me incorrect answers. The previous tutor raised their suspicion that these problems will be graded, I can assure you these are just problems for me to practice NOT for a grade, I just wanted to see if i get the right answer.

THIS CAN NOT BE HAND DRAWN!

In any manufacturing process, reaction monitoring ensures that a chemical reaction proceeds as expected. Table 1 shows the monitoring data for the formation of chlorohexane, collected using a technique called gas chromatography. Note that the concentrations of the chlorohexane solutions are given in millimoles per litre (mmol l–1). The abbreviation mM (millimolar) is frequently used. Plot a graph of the data in Table 1. The graph should be drawn on graph paper or use fine grid if it’s drawn on Excel. Elapsed Time/Hours  Concentration of Chlorohexane/mM 0 0 2 40 4 65 6 80 8 90 10 95 12 99
