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 hydrochloric

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

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.

What methods of Index Number calculation is used to calculate Cost of Living Index (CLI). An index number measures the relative change in the price‚ quantity‚ value or some other item of interest from one time period to another. It is found by calculating the ratio of the current value to the value at another time point or at a different geographical location. The different types of simple index that are used are - Price Relative‚ Quantity Relative‚ Value Relative. A price index is a weighted

For the percentage yield is 39.08% which is less than and not 100%‚ by this‚ it can be concluded that the reaction is non-stoichiometric. The low yield can be explained by the following ways: The presence of reversible reaction-for the reaction between ethanol and ethanoic acid‚ it is reversible and which is only considered to be irreversible for simplicity of calculations. For reversible reaction like this‚ the ethanol and ethanoic acid will not be totally converted to ethyl ethanoate but until

learned to find interval estimates for two population parameters‚ a population mean and a population proportion. Explain the meaning of an interval estimate of a population parameter. An interval estimate for a specified population parameter (such as a mean or proportion) is a range of values in which the parameter is estimated to lie. In Chapter 6‚ you were assigned to find interval estimates for a population mean and a population proportion. b) Is finding an interval estimate an example of inferential
