Question: You perform a lab where you are instructed to observe the characteristics of a lipid molecule in oil and water and are told to conduct 3 trials each time for the lab. You noticed that you get the same observations for all 3 trials for the lab. Explain in detail why you were asked to complete 3 trials? Why were you not asked to complete 1 trial?

Expert Solution

Lab trials are repeated three times as this ensures a 66% probability accuracy of the obtained results over performing the experiment ones. Multiple measurements or observations of a single experiment would increase the confidence levels of the result and aid in the elimination of manual and technical errors. Also 3 trials were asked to be performed in order to ensure that the protocol used results in reproducible outcomes. Another reason for repeated trials of the experiment is to use the obtained results to perform statistical analysis and determine parameters such as mean, standard deviation and variance which are then used to determine the significance of the data and to determine if the results are good enough to derive a logical conclusion.Also repetition ensures that the results obtained were not due to other ambient conditions such as temperature, pH etc. in the first trial and are genuinely results of the intended reactions.

Post-‐Lab to Accompany the Grignard Synthesis of Triphenylmethanol You were instructed to add the bromobenzene in increments during the Grignard preparation to prevent an unwanted side reaction. What would the product of that reaction be (show structure also)? How was it removed during work-‐up from the triphenylmethanol product?

For this portion of the lab you will design the solution so that you perform some conditional tests. For this lab: 1. You will validate input to ensure that the user enters inputs within a certain range or larger than a certain minimum value. You will validate the inputs as follows: (LO 1, 2, 3) a. The user cannot enter a negative number for: i. Miles to kilometers ii. Gallons to liters iii. Pounds to kilograms iv. Inches to centimeters...

Suppose we observe two stocks with the following characteristics: StockExpected returnBetaK20%1.6L12%0.9a. An asset is said to be overvalued if its price is too high given its expected return and risk. The risk-free rate is currently 6%. Is one of the two stocks overvalued relative to the other?

If you were to perform this reaction in a lab, you would make far less than the theoretical yield of product due to a wide range of outside factors. We can compare the actual yield to the theoretical yield to calculate the percent yield: percent yield=actual yieldtheoretical yield×100% Keep in mind that the percent yield can be calculated using any unit of mass or moles, so long as they are the same. For example, you can divide moles by moles,...

Design an experiment that you could perform in our lab to determine the coefficient of kinetic friction and static friction and to compare the coefficient of kinetic friction and static friction. A good design should include details of the materials and equipment needs, the experimental procedure, including precautions, the types of data you will collect, how the data will be represented and analyzed, and how you will determine the accuracy of your experimental result(s).
