The aim of this audition is to investigate the immersion of the react termination is a factor that affects the per centum government issue of the return. The hypothesis of the experiment is the higher submerging of the react firmness the lower the share yield of the product. By doing the reaction of diametrical denseness of the Cu (NO3)2 solutions react with the metal Mg. All the result shows that the higher submergence of the Cu (NO3)2 solution the lower the percent yield of the product Cu. So there is no relationship amidst concentration of the react solution and percent yield of product.
For the result, the norm mount of the product Cu in 0.25M solution reaction is 0.27g. The add up ken of Cu in 0.5M reaction is 0.28g. The average multitude of Cu in the 0.75M reaction is 0.27g, and the average mass of Cu in the 1.00M reaction is 0.26g. For the graph the result of the product Cu, the concentration of the react solution Cu (NO3)2 increase, the mass of the product Cu decrease. By calculate the percent yield of assorted concentration Cu (NO3)2 solutions react with Mg. The average percent yield of the different concentration solution 0.25M Cu (NO3)2 and 0.75M Cu (NO3)2 are 103.85 %. The average percent yield of 0.50M Cu (NO3)2 is 107.69%. The average percent yield of 1.00M Cu (NO3)2 is 100 %.



The concentration of the solution Cu (NO3)2 increase, the percent yield of the product Cu decrease.
There was not a relationship between variable, because the reactants is fixed before they are react. The mass of the metal Mg is 0.1g in severally trial, and the volume of the solution 0.25M Cu (NO3)2, 0.5M Cu (NO3)2, 0.75M Cu (NO3)2 and 1.00M Cu (NO3)2 is 20ml in each trial. The time of the reaction react is the same. So, the Mg react with the different concentration Cu (NO3)2 result produce the same make sense of Cu and Mg (NO3)2. There was no relationship between the independent and dependent variable.
There are sources of error will affect the accuracy of the result. The precipitate...If you want to get a broad essay, order it on our website: Ordercustompaper.com
