magnesium Oxide Aim: Equipment: Method: 1. Heated the crucible and eyehat strongly for 5 min everyplace a blister Bunsen burner. Allowed to cool. 2. Weighed the crucible and lid 3. Thoroughly cleaned the surface of the Mg thread with steel woolen. 4. Recorded the appearance of the cleaned Mg. 5. Coiled the cold shoulder of Mg ribbon so that it fitted inside the crucible. Weighed the crucible, lid and milligram ribbon. 6. Placed a pipe clay triangle everyplace the Bunsen burner and care mounty het the crucible without the lid until the atomic number 12 began to glow then put the lid on with gibe of tongs before it burst into flames. 7. Once the lid was in place, heated strongly for about 10 mins lifting the lid now and again to take for oxygen. 8. Removed the lid and heated for a advertize 5 mins to ensure complete reaction. 9. Replaced the lid and allowed to cool. Reweighed the crucible, lid and milligram oxide. Results: bearing Empty crucible and li d melting pot, lid and atomic number 12 ribbon Magnesium Ribbon Crucible, lid and magnesium oxide Magnesium Oxide group O 2Mg + O2 = 2MgO Calculations: Moles of Mg = the great mutual / wedge plentitude = 0.35 / 24.3 = 1.44 x 10-2 groyne Moles of MgO = plenty / Molar loudness = 0.51 / 40.3 = 1.27 x 10-2 mol Moles of O2 = Mass / Molar Mass = 0.16 / 32 = 0.50 x 10-2 mol deduction: The empirical convening for Magnesium oxide is MgO.

Magnesium Oxide Craville Studies Page 1 of 2 To pick up the empirical formula using molar bunch of Magnesium oxide. 1 Strip of Mg ribbon Crucible and lid Pipe clay triangle Tripod Matches Steel wool coat tongs Bunsen! Burner Electronic scales Safety glasses Mass (g) 30.47 30.82 0.35 30.98 0.51 0.16 Evaluation: Overall it was fairly successful. Theoretically the moles of Magnesium should slay up the derive of moles of Magnesium oxide produced. However it is not. This is due to a number of reasons. To begin with, the electronic scales only measure to 0.01 of a gram. That, match with the small nature of the masses means on that point is a larger percentage...If you want to get a full essay, rule it on our website: BestEssayCheap.com
