Imagine you are running a new company that wants to start small and then scale. As the manager, you start out as the only full-time employee and you have a part-time support staffer and a part-time marketing employee. 1. At the beginning of your operations (year 1), the price of your product is $100. Your competitors are charging $110. Your direct costs are $60/unit ($40 labor, $20 materials). Your monthly overhead is as follows: facilities all-in $3,000, management $10,000, sales-marketing...

what is the theoretical yield of anisalacetophenone and
dibenzalacetone formed? thank you.
The Aldol Condensation Precautions: Acetone, ethanol and acetophenone are flammable; work in a fume hood. Sodium hydroxide is a strong base and can cause severe skin burns and eye damage. Safety goggles are required. Gloves are recommended. Purpose To carry out two Aldol condensation reactions in which no heat is needed to obtain the condensation product. The two reactions differ in the number of enolizable protons at the...

3. To make a buffer solution, you can start with a solution of a known number of moles of the base form (A) and add a strong acid until you have neutralized the correct number of moles of the base to have the correct A HA ratio for the buffer you require. For the example using HF in the background information: a. How many moles of the base form (A) are required to start? HINT: The acid form (HA) will...
