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…

Hello, I hope you are doing well on this fine day. For the following quetion please read carefully the question and instruction. PLEASE ANSWER QUESTION IN 20 MINTUES NOT MORE PLEASE AND THANK YOU. If you do answer the question correctly and post it in the next 20 minutes, NO NEED TO SHOW ALL THE WORK, I JUST WOULD LIKE THE CORRECT ANSWER AS SOON AS POSSIBLE. I will write a wonderful and generous feedback/review/rating about you. NOT ONE HOUR!!! THIS IS A TEXTBOOK QUESTION HURRRY UP PLEASE You perform the conductivity experiment as described in the lab manual using NaCl solutions of known concentrations. You plot the conductivity of your solutions (μS/m) as a function of the concentration (mol/L). You make a trendline with an equation of y = 1.42 x 105 x + 9.94 x 102. You then test the conductivity of an unknown sample of chicken broth. If the chicken broth conductivity is 7.12 x 103 μS/m.  What is the concentration of NaCl in the broth in mol/L?

Retype each equation into the adjacent box. Use the X' button for superscripts and the X, button for subscripts. Use the right and left arrow keys on your keyboard to get out of either the superscript or the subscript mode. 2Na + Cl, 2NaCl L(s) + 2e 21¯(aq) W étv 26 MacBook Air DII DD F12 F11 F10 F9 80 F8 F7 F6 F5 F3 F4 * & dele %23 $ 9 く

Please help

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.

What is the total amount (in mol) of ions in solution when 34.7 g of the ionic solid Ba(OH)2·8H2O completely dissolves in water? The molar mass of Ba(OH)2·8H2O is 315.46 g/mol.

This assignment is designed to help you learn how to determine total costs by combining direct and indirect costs for a particular department. In this GHA, you will be determining the total costs for three departments: (1) Physical Therapy (2) Occupational Therapy and (3) Speech Therapy. To determine the total costs, you will need to add the direct costs to the indirect costs using the template provided below. Please use the example provided in the assignment description if you find that you need some support understanding the required calculations. DIRECT COSTS The direct costs for each department are easily identifiable, because they are the costs that are directly attributable to the department. The direct costs are as follows: Physical Therapy (PT) Occupational Therapy (OT) Speech Therapy (ST) Total Direct Costs INDIRECT COSTS The indirect costs will need to be allocated to Physical Therapy (PT), Occupational Therapy (OT), and Speech Therapy (ST). The indirect costs in this…
