Experiment to find the ratio of Magnesium to Oxygen in Magnesium Oxide.

Extracts from this document...

Introduction

Experiment to find the ratio of Magnesium to Oxygen in Magnesium Oxide Aim The aim of this experiment was to find the amount of carbon dioxide given off when reducing copper carbonate to copper oxide. You must find the amount of products and reactants. To do this it is possible to use the following method Method Equipment: * Test tube * Five spatula's of copper carbonate * Electric balance * Bunsen burner * Spatula * Test tube tongs * Test tube holder Instructions: 1. Select a test tube. 2. Clean the test tube to make sure that there will be no other reactants inside the test tube other than what is required. ...read more.

10. Once it appears that the reactants have finished reacting (when the reactants stop bubbling) turn off the Bunsen burner and place the test tube in the test tube holder to allow the test tube to cool. When the test tube is cool weigh it using the electric balance (the weight should have decreased from step five). 11. Repeat steps six to ten until the final weight remains constant, thus all the reactants have been used up. Calculations Weight in grams Experiment 1 Experiment 2 Test tube 28.32 29.08 Test tube containing copper carbonate 36.96 32.9 Crucible and lid containing copper oxide 34.3 31.78 Copper carbonate 8.64 3.82 The weight of the test tube containing copper carbonate minus the weight of the test tube Copper oxide 5.98 2.7 The weight of ...read more.

Conclusion

results in the tables concerning the first experiment it is possible to see that for one mole of copper carbonate 0.86 moles of carbon dioxide should be given off. From the results in the tables concerning the second experiment it is possible to see that for one mole of copper carbonate 0.83 moles of carbon dioxide should be given off. Sources of error Possible sources of error include: * The test tube may not have been completely clean therefore there will have been reactants in there that have not been included in the calculations. * The electric balance may not have been working correctly or may have given results that were not precise enough thus making the calculations wrong. * Some copper oxide may have escaped therefore making the amounts wrong ...read more.

  2. The role of mass customization and postponement in global logistics

    The notion of manufacturing postponement is to retain the product in a neutral and noncommitted status as long as possible in the manufacturing process. This means to postpone differentiation of form and identity to the latest possible point. The notion of logistics postponement is to maintain a full-line of anticipatory inventory at one or a few strategic locations.

    to cool for aproximatley 1 minute whilst weighing it and then reheat for another 2 minutes. The reason we reheated the test tube was to be certain that all the zinc carbonate had been compltety heated. Now repeat process for 2.5g, 3g, 3.5g, and 4g of calamine.
