ZA + 3B → C 4.0 mol A is mixed with 4.0 mol B and a reaction takes place. Which reactant is limiting? Neither is limiting because equal amounts (4.0 mol) of each reactant are used. b. a. A is limiting because 2 is smaller than 3 (the coefficients in the balanced equation). c. A is limiting because there are 2 mol of it but 4.0 mol are needed. d. B is limiting because 3 is larger than 2 (the coefficients in the balanced equation). B is fimiting hecause there are 40 mot of it but 6.0 mot needed

Q5. As part of the aspirin synthesis lab, the orgo students also had to perform the following calculation to demonstrate their knowledge. Are you able to help them work this out? Saponification is a process in which soap is produced from the chemical reaction between animal fat (triglycerides) and a strong base such as KOH. An example of such a balanced chemical reaction is shown here: C51H98O6 + 3KOH à C3H5(OH)3 + 3C16H31O2K Triglyceride                                        Soap If, during the saponification reaction, 231.5 g of C51H98O6 is mixed with 231.5 g of KOH and 160 g of soap is produced: Calculate the theoretical yield of soap (in grams), C16H31O2K, and indicate which species is the limiting reactant. Provide your answer to 2 decimal places (5). Calculate the percent yield for this reaction. Provide your answer to 1 decimal place (1). Show ALL steps and equations involved in your calculations. Remember to label all steps clearly and use appropriate units.

A patient was taking codeine 60 mg PO QID. According to standard opiate conversions, 20 mg of codeineis equivalent to 3 mg of hydrocodone. What is the equivalent amount of hydrocodone is the patient receiving per day?
