16 The odor of fish is due primarily to amines, especially methylamine (CH3NH₂). Fish is often served with a wedge of lemon, which contains citric acid. The methylamine reacts with the citric acid to form an odorless product, methylammonium citrate, thereby making less-than- fresh fish more appetizing. K₁ for CH3NH₂ = 4.407 × 10-4 CH₂NH₂ (aq) + H₂O(1)⇒ CH₂NH3(aq) + OH(aq) A. B.

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 NaOH. An example of such a balanced chemical reaction is shown here:C57H110O6 + 3NaOH à C3H5(OH)3 + 3C18H35O2NaIf, during the saponification reaction, 228.5 g of C57H110O6 is mixed with 211.7 g of NaOH and 180 g of soap is produced: a. Calculate the theoretical yield of soap (in grams), C18H35O2Na, and indicate which species is the limiting reactant. Provide your answer to 2 decimal places. b. Calculate the percent yield for this reaction. Provide your answer to 1 decimal place. Show ALL steps and equations involved in your calculations. Remember to label all steps clearly and use appropriate units
