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

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.

calculate the new price. The fruit stall has 100 peaches initially but 10 peaches are rotten. It means the number of remaining peaches is 90 units. Therefore‚ the question provides the factors such as initial quantity‚ new quantity‚ initial price which are 100‚ 90‚ 1 respectively. Let the new price be x. Therefore‚ we will choose $1.2 per unit as the new price to sell the remaining peaches. 4.4aii. Case 1: If I do not discover the rotten peaches‚ the quantity demanded is 100. Case

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
