Here is the procedure: Charge a 35 mL microwave reaction vessel with 12 mL of your vegetable oil and 3 mL of methanol (methanol to vegetable oil approximately at a molar ratio of (6 : 1)). Add 0.12 grams of KOH to the mixture. Heat the solution to 85 °C for 5 minutes with stirring. (Note about microwave accelerated synthesis: The reaction is traditionally performed at 65 °C for 30 minutes under reflux in a vessel open to the atmosphere. Question: Explain the rate acceleration observed in the microwave experiment.

A student use the same protocol as in the lab manual to extract 4 chloroanilline, benzoic acid and naphthalene. Below are the steps he took Step 1 - Dissolve all three in 15 ml ether and place in separatory funnel Step 2- Add 15 ml of hydrochloric acid and mix well Step 3 - Isolate the aqueous layer and add sodium hydroxide which resulted in a precipitate Step 4- Add 15 ml of sodium carbonate to the ether layer and mix Step 5- Isolate the aqueous layer and add hydrochloric acid, which resulted in a precipitate. Step 6- dry the ether layer and collect the solid that is left

answer question 2.

If 80% of a desired compound is extracted into the organic phase in each step (leaving 20% in the aqueous layer), how many extractions are necessary to ensure that at least 99% of the compound has been recovered in the organic phase?      1 extraction     2 extractions     3 extractions     4 extractions

Glutamate-5-semialdehyde dehydrogenase converts glutamate-5-phosphate to glutamate-5-semialdehyde using NADH as a cofactor. Draw curved arrows for each step of the reaction to show this conversion. H H O `NH2 `N´ H3N + NAD* H phosphate and NAD* Z-R
