IlI. Preparation of Synthetic Eugenol (10 pts) Eugenol, the main component of clove oil, can be prepared from heating 2-allyl guaiacol (in the absence of oxygen) to temperatures>205 °C. In practice, however, it is most cost effective to extract eugenol from cloves, its natural source. Given a weight percentage of eugenol in cloves at-15%, calculate the minimum mass of cloves one needs to obtain 1.00 g of eugenol as product? Report your answer below. Show your...

You have a sample (Sample X) which is a mixture of +/- Carvone. The solution was made by dissolving 4.50 g of the sample in enough methanol to bring the volume of solution to 10,0 ml. Some of the solution is placed in a 100 cm polarimeter cell and its optical rotation is measured at 25°C using light of the sodium D line wavelength (589.6 nm). The observed rotation is...

QUESTION 5 Suppose you obtained one sample from the same data generating process as above (Y = 2 + 3x+ u), and your estimate β 1 (the estimated X coefficient) was 2.107. Which of the following best describes whether the estimator is biased? The estimator is biased because the estimate 2.107 is too far below the population parameter of 3 The estimator is not biased because the estimate 2.107 is within 30 percent of the population parameter 3. We do...

As part of Lab 11 you will make and standardize a solution of NaOH(aq). Suppose in the lab you measure the solid NaOH and dissolve it into 100.0 mL of water. You then measure 0.1993 g of KHP (204.22 g/mol) and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add a couple of drops of phenolphthalein indicator. You titrate this with your NaOH(aq) solution and find that the...
