The percent yield of meso-1‚2-dibromo-1‚2-diphenylethane was calculated to be 66.36% and with a melting point of 235.1°C. Therefore‚ it can be concluded that this experiment was successfully conducted as the percent yield obtained is only 33.64% off from the equilibrium point‚ and because the melting point met the literature value. The percent yield for the product was less than 100%‚ indicating that were experimental errors‚ such as an undesirable side reaction‚ or more likely‚ an incomplete reaction

17 g Determine the percent yield of NaCl in your experiment‚ showing all work neatly in the space below. (5 points) 7.17 g / 8.8197 g = 0.81295 = 81% If you had not heated the product long enough to remove all of the water‚ explain in detail how that would have specifically affected your calculated actual yield and percent yield. (5 points) The product’s mass would be greater making the calculations adjust. If my actual yield is greater‚ then so would my percent yield.

In Defending the One Percent‚ Gregory Mankiw begins with difficult to imagine experiment where a perfect economic equality exist and one day the utopia is disturbed by a genius entrepreneur with an idea of a new product. Because of the magnificent idea everyone would like to buy the product in a voluntary exchange‚ which results in an extreme unequal distribution of income. Since there are no policies that follow the Pareto criterion‚ the question is if the government should shift to a progressive

Purpose The purpose of the experiment is to determine the percent yield of the precipitate; by performing double displacement reaction between solutions of two different compounds. Introduction First of all when making a solution of two different compounds; there will many variables that can be considered during the experiment. However‚ the variables are controlled variables. Controlled Variables ∙amount of water that will be dissolved with the compound (amount of water until the compound is

The percent yield was calculated to be 171% indicating a source of error. The high percent yield was due to the product being wet since we did not have enough time to dry the product with the vacuum filter—since we had to evacuate the building due to the fire alarm. If we were able to vacuum filter our product more‚ the percent yield would be close to 100%. 1. Assign the peaks in your NMR spectrum of your salicylic acid. See NMR spectrum on back 2.

Mesta Dr. Mbah December 6‚ 2012 Percent Yield of a Chemical Reaction Introduction Yield is the quantity of product in a chemical reaction‚ the theoretical yield of a reaction can be calculated using mole ratios from the balanced chemical reaction. The actual yield has to be obtained and measured in a laboratory. It may be usual to often find the actual yield to be less than the theoretical yield due to many different factors. This gives rise to the concept of percent yield. Sodium bicarbonate and

Lab experiment 12 Percent of water in a hydrate The goal of Experiment 12 was to learn how to calculate the percent of water (by mass) in barium chloride and an unknown hydrate salt‚ as well as properly calculating the water of crystallization for the unknown hydrate salt. A hydrate salt is composed of anions (-) and cations (+) surrounded by a fixed number of water molecules‚ called water of crystallization. The hydrate decomposes upon heating and
