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

Perhaps‚ therefore‚ we should start by considering what we mean by a ‘theory’. Theory.‚ which has a Greek root‚ .Theoria. meaning to .behold or view.. A popular definition given by Kerlinger defines theory as .a set of interrelated constructs (concepts)‚ definitions and propositions that present a systematic view

unconscious when the mind redirects a thought or word dangerous or unacceptable and substitutes it with a more affable thought or word. Condensation; where all the different elements‚ bits and pieces of thought and dreams combine into one to make sense. In this way they can stand for several different thoughts‚ feelings‚ wishes‚ ideas‚ etc. For Freud‚ condensation and displacement / substitution were used as a defense mechanism to contain aggressive and sexual impulses and hide the true unconscious

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
