PR OCEDURE Before beginning‚ set up a data table similar to the Data Table: Experiment Results in the Lab Report Assistant section. This experiment will create a reaction of sodium carbonate and calcium chloride dihydrate to produce a precipitate of calcium carbonate. This formula is: Na2CO3(aq) + CaCl2. 2H2O(aq) à CaCO3(s) + 2NaCl(aq) + 2H2O 1. Put on your goggles. 2. Weigh out 1.0 g of CaCl2·2H2O and put it into the 100-mL beaker. Add 25 mL of distilled water and stir to form the calcium

health. The purpose of this experiment is to extract and find quantitative amount of Beta-carotene from a carrot sample. The raw product(carrots) was extracted using simple distillation. The purity of the product will be characterized using percent yield‚ thin layer chromatography‚ Beer’s Law‚ and UV-vis. Beer’s law is used because in this experiment we are comparing our extraction of B-Carotene to the Stock B-Carotene. Beer’s law shows that absorbence of light at a specific wavelength is proportional

reaction 2Al + 2CuCl₂ → 3Cu + 2AlCl₃ we carried out this experiment and determined that the limiting reactant was CuCl₂ and that the aluminum was in excess. We also determined the percentage yield of copper. Purpose: The purpose of this experiment was to determine the limiting reactant and percentage yield of the reaction that took place between Copper (ll) Chloride and Aluminum. Hypothesis: 2Al + 3CuCl₂ → 3Cu + 2AlCl₃ m= 0.25g m=

the experiment‚ a yield of 0.21 g of a pure white crystal were collected from the Buchner funnel‚ and when compared to the calculated theoretical yield‚ 0.82 g (found in Calculations 1.A)‚ a percent yield of 25.4% can be calculated for this procedure. Although this value may not seem favorable for this procedure‚ when compared to the expected value described by the laboratory manual‚ which was 0.4 g‚ it can be seen that the procedure performed better than the current percent yield may illustrate.
