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

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

8 The Cost of Capital 236 CHAPTER 8—THE COST OF CAPITAL TRUE/FALSE 1. Capital refers to items on the right-hand side of a firm’s balance sheet. 2. The component costs of capital are market-determined variables in as much as they are based on investors’ required returns. 3. The cost of debt is equal to one minus the marginal tax rate multiplied by the coupon rate on outstanding debt. 4. The cost of issuing preferred stock by a corporation must be adjusted to an after-tax figure because

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.

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
