Identify each activity, a to f, as an observation, a hypothesis, an experiment, or a conclusion. At a popular restaurant, where Chang is the head chef, the following occurred:
a. Chang determined that sales of the house salad had dropped.
b. Chang decided that the house salad needed a new dressing.
c. In a taste test, Chang prepared four bowls of sliced cucumber, each with a new dressing: sesame seed, olive oil and balsamic vinegar, creamy Italian. and blue cheese.
d. Tasters rated the sesame seed salad dressing as the favorite.
e. After two weeks, Chang noted that the orders for the house salad with the new sesame seed dressing had doubled.
f. Chang decided that the sesame seed dressing improved the sales of the house salad because the sesame seed dressing enhanced the taste.

- Assign this spectrumarrow_forwardRedraw the tripeptide with or without its acidic hydrogensto demonstrate where the total charge of -2 comes from: *see imagearrow_forward2. Consider the data below to answer the following questions. Cyanohydrins are important intermediates in the synthesis of α-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated. OH CH-COOH 0 HO CN C H30* C. H H HC N NaOH H₂O C=O 0 cyanohydrin H + NaCN + H₂Oarrow_forward

Show all nonzero formal charges and all nonbonded electrons in each step. Species not involved in a particular step do not need to be included in that step, and resonance forms do not need to be shown.
