Programming language: PYTHON Prompt: You will be creating a program to show final investment amounts from a principal using simple or compound interest. First, get a principal amount from the user. Next, ask the user if simple or compound interest should be used. If the user types in anything other than these options, ask again until a correct option is chosen. Ask the user to type in the interest rate as a percentage from 0 to 100%. Finally, ask the...

Pre-lab Questions:
Importance A one-step preparation of aspirin from its precursor, salicylic acid, via an ester formation illustrates one of synthetic organic chemistry's most important uses, making the drugs that treat all types of illnesses. OH HOOH Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the ancient Greeks as a treatment for pain...
