Chemistry You are the only doctor in a clinic that is cut off from the outside world by violent storms and landslides. A 30-year-old woman suffering from tachycardia is brought in. You can see she is likely to die without treatment, and although you have very few drugs, you have propranolol, a beta blocker, in injectable vials. You decide to give the woman intravenous propranolol. The pharmacokinetics of propranolol include a clearance of 50L/hour and a half-life of 3 hours. If an intravenous infusion of propranolol is started at a rate of 0.5mg/minute, approximately how long would it take to reach 93.75% of the final steady-state concentration? 3 hours 50 minutes It would depend on the dosage 12 hours

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?

Estrogens are female sex hormones, the most potent of which is B-estradiol. OH AYA Но B-Estradiol In recent years, chemists have focused on designing and synthesizing molecules that bind to estrogen receptors. One target of this research has been nonsteroidal estrogen antagonists, compounds that interact with estrogen receptors and block the effects of both endogenous and exogenous estrogens. A feature common to one type of nonste- roidal estrogen antagonist is the presence of a 1,2-diphenylethylene with one of the benzene rings bearing a dialkylaminoethoxyl substituent. The first nonsteroidal estrogen antagonist of this type to achieve clinical importance was tamoxifen, now an important drug in the treatment of breast cancer. Tamoxifen has the Z configuration shown here. NMeg A B NMeg ? ОН Tamoxifen Propose reagents for the conversion of A to tamoxifen. Note: The final step in this synthesis gives a mixture of E and Z isomers.

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…

Search for Life Transfer Task 2 - Salt Substitute The American Heart Association says that at greater risk for high blood pressure as a result of eating salt. According to their website, "as little as one extra gram (half a teaspoon) of table salt could raise blood pressure as much as 5 mm Hg" compared to people who do not have this gene (heart.org, 2021). Table salt is made from Na & Cl ions, and there may be substitutes for it to be used in cooking that do not contain sodium. Sodium (Na) is the damaging part of table salt. Americans may be Nu Sait TSUESTTUTE Answer the prompts below to address the following question: What could be a substitute for sodium in table salt? 1. Which of the following questions could help you determine which element could be used as a substitute for sodium in table salt? (choose all that apply A. Do some elements have the same number of valence electrons as sodium? B. Are some elements more common on Earth than sodium? C. Do some elements combine to form…

Benzoic acid and water were added to the test tube labeled "b.a." After stirring the mixture, sodium hydroxide (NaOH) vas added until the solid disappeared. Finally, hydrochloric acid was added drop by drop until blue litmus paper turned red. The solid present in the test tube after the addition of HCI is most likely: benzoic acid benzyl acetate O benzyl chloride sodium benzoate

1) Hydrolysis of Methyl Salicylate: Methyl Salicylate (C8H8O3) + sodium Hydroxide (NaOH) -> sodium Salicylate ( NaC7H5O3) + Methanol (CH3OH) 2) Acidification of Sodium Salicylate: Sodium salicylate (NaC7H5O3) + HCL -> Salicylic acid (C7H603) + sodium chloride (NaCL) Could you find the theoretical yield for me? 2.15g of methyl salicylate was used. 25ml of sodium hydroxide (2m solution) was used for hydrolysis and 2ml of hydrochloric acid was used for the acidification. This produced a yield of 1.53g of salicylic acid.
