which indicates that 2-chloro-2-methylbutane was the only product of this reaction. The theoretical yield was calculated using 2-methyl-2-butanol as the limited reagent in the reaction‚ and was found to be 7.80 grams of 2-chloro-2-methylbutane. The experimental yield that was retrieved was found to be much less‚ at 1.84 grams. The percent yield was calculated to be 23.60% utilizing those values. This percent yield is quite a poor value and would be attributed to several factors in the experiment.

Abstract: All the materials were measured and weighed. It was found in the experiment that the yield of copper hydroxide in 40%. Introduction: The copper (II) sulphate is then placed in 100 mL of distilled water. Then 20 mL of CuSO4 is measured and placed 100 mL of distilled water. This can later be weighed to determine the mol of CuSO4 and the mol/L concentration. Then this was used to find out how many mL of 0.5 NaOH solution is needed to react completely with all the copper (II)

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 should be 100%‚ as this means that you have recovered 100% of that material. A yield over 100% would mean that the substance still has some traces of another material that is adding additional mass. Ex. The iron filings having some sand particles leftover. A yield under 100% would mean that some of the substance was not recovered‚ it could have been lost (spilled) or found in another substance (not separated completely). The percent yields may give some insight into what occurred during

variety of factors that impact the shape of the yield curve but monetary authorities influence greatly the shape of the yield curve .Monetary authorities influence the shape of the yield curve by initiating either a contractionary monetary policy or an expansionary monetary policy.A yield curve is a line that plots the interest rates‚ at a set point in time‚ of bonds having equal credit quality‚ but differing maturity dates. The most frequently reported yield curve compares the three-month‚ two-year‚ five-year
