Organic Chemistry I ASSIGNMENT: Convert isolated eugenol to an ester on a small scale, and purify by recrystallization. Characterize the product by infrared spectrometry, mass spectrometry and nuclear magnetic resonance spectrometry. Compare the analytical data of your product with that of your starting material, eugenol.
What is the mole fraction of urea, CO(NH2)2, in a solution prepared by dissolving 5.6 g of urea in 30.1 g of methanol, CH3OH?
Discussion Question 1 A concentrated phosphoric acid solution is 85.5% H3PO4 by mass and has a density of 1.69 g/mL at 25°C. What is the molarity of H3PO4? What is the mole fraction of urea, CO(NH2)2, in a solution prepared by dissolving 5.6 g of urea in 30.1 g of methanol, CH3OH? How will an […]
Using the temperature change (AT) and mass of water from Table 1, and the specific heat capacity of water (1.00 cal/WC) and Equation 1, determine the quantity of heat (q) released by combusting each food.

In the collection of the rate data for the experiment, when do START TIME and STOP TIME occur for each kinetic trial in Table 24.1?
Experiment 24 Prelaboratory Assignment A Rate Law and Activation Energy Three data plots are required for analyzing the data in this experiment, two plots from the kinetic trials outlined in Table 24.1 and one plot from Part E. From each data plot, a value is determined toward the completion of the analysis of the kinetic […]
