06.03 Calorimetry: Lab Report Before You Begin: You may either copy and paste this document into a word processing program of your choice or print this page. Part I The Dissolving of Solid Sodium Hydroxide in Water Procedure: 1. Measure out approximately 200 mL of distilled water and pour it into the calorimeter. Stir carefully with a thermometer until a constant temperature is reached. Record the volume of water and the constant initial temperature of the water on your data table.

exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice and baking soda‚ammonia and vinegar‚ and finally‚ hydrochloric acid and sodium hydroxide. I did each experiment when the acid was 0‚ 20‚ 40‚ 60‚ and 80;all in degrees Celsius. Therefore‚ I could compare the exothermic reaction with the endothermic reaction at each temperature. For the Lemon Juice + Baking

Magnesium with Hydrochloric acid and collect Hydrogen. The grams of the produced Hydrogen will be calculated and compared to the theoretical yield of Hydrogen. ! Controlled Variables ! Mass of Magnesium Ribbon This will be kept constant as the objective is to determine the Gas Constant (R). If this is influenced‚ then the overall yield will be affected as the amount of hydrogen produced will be altered. The mass will be controlled using a Scale. Amount of Hydrochloric acid The

Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants was determined

Pour about 2.0 mL of lead (II) nitrate into the test tube. Add 5 to 10 drops of potassium iodide solution to the test tube and record your observations of the reaction. 7. 8. 9. Magnesium metal and hydrochloric acid solution 10. Place one scoop of magnesium turnings into the test tube. Add hydrochloric acid slowly and observe the reaction. Next‚ place a burning splint near the mouth of the test tube to test for the presence of hydrogen gas. 11. 12. 13. Electrolysis of water 14. Use a Utube with electrodes at each end

How fast is your reaction? Part 1 – How temperature affect the rate of reaction Chemical equation Magnesium + hydrochloric acid → magnesium chloride + hydrogen Mg + 2HCL → MgCl2 + H2 Graph Conclusion and questions 1. What factors/variables did you keep the same in this experiment? * We kept the same volume of hydrochloric acid (10 cm3) and the magnesium ribbon (5cm) because that way we could get a fair test experiment. We also repeated

(0.01 mol/L) concentrated hydrochloric acid‚ HCl (aq) (12 mol/L) (for teacher use only) Procedure 1) Put on your safety goggles‚ apron‚ and protective gloves. 2) Put 3 test tubes in a test-tube rack. From the dropper bottles‚ place 2 drops of butan-1-ol in the first test tube‚ 2 drops of butan-2-ol in the second test tube‚ and 2 drops of 2-methylpropan-2-ol in the test tube. 3) Under the fume hood‚ your teacher will add 10 drops of concentrated hydrochloric acid to each of your 3 test
