- 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 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 % 1 1000. mg 0 mg 200. mg 150. mg 0 483. mg 2 250. mg 0 mg 600. mg 378. mg 316. mg x10 μ ロ・ロ %] %]arrow_forwardShow work. don't give Ai generated solutionarrow_forward11:48 PM Fri Dec 13 < ... ළා 52% AA -fleet02-xythos.content.blackboardcdn.com ⇓ Ċ Lab Report Assistance Content C OWLv2 | Assignment...

- Please don't use Ai solutionarrow_forwardNonearrow_forwardSynthetic natural gas (SNG) is a methane-containing mixture produced from the gasification of coal or oil shale directly at the site of the mine or oil field. One reaction for the production of SNG is: 4 CO (g) + 8 H2 (g) → 3 CH4 (g) + CO2 (g) + 2 H2O (g)Use the following thermochemical equations to determine ΔHo for the reaction as written. C(graphite) + 2 H2 (g) → CH4 (g) H2 (g) + 1/2 O2 (g) → H2O (g) C(graphite) + 1/2 O2 (g) → CO (g) CO(g) + 1/2 O2 (g) → CO2 (g) ΔHo = -74.8 kJ ΔHo = -285.8 kJ ΔHo = -110.5 kJ ΔHo = -283.0 kJ 5b.

- The PCC (1-piperidinocyclohexane carbonitrile) content of a clandestinely synthesized PCP (phencyclidine) sample can be determined by precipitating and weighing the product: PCC + Phenylmagnesium Bromide → PCP MW = 186.258 g/mole MW = 181.31 g/mole MW 243.387 g/mole In one analysis, 0.702 g of sample was dissolved in 25 mL of cylcohexanone and 1 g of phenylmagnesium bromide was added. After 25 minutes, the precipitate was filtered, washed with acetone, dried at 110°C, and found to weigh 0.869 3 grams. Find the recovery in wt% of PCC in the sample. In another analysis, the same sample was found to contain 5.17% of another impurity.
