magnesium Oxide Aim: Equipment: Method: 1. Heated the crucible and eye eye chapeau strongly for 5 min everyplace a acrimonious 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 stroke of Mg ribbon so that it fitted inside the crucible. Weighed the crucible, lid and mg ribbon. 6. Placed a pipe clay triangle everyplace the Bunsen burner and care safey het the crucible without the lid until the atomic number 12 began to glow then put the lid on with orthodontic braces of tongs before it burst into flames. 7. Once the lid was in place, heated strongly for about 10 mins lifting the lid from time to time to take for oxygen. 8. Removed the lid and heated for a hike up 5 mins to ensure complete reaction. 9. Replaced the lid and allowed to cool. Reweighed the crucible, lid and magnesium oxide. Results: bearing Empty c rucible and lid melting pot, lid and magnesium ribbon Magnesium Ribbon Crucible, lid and magnesium oxide Magnesium Oxide group O 2Mg + O2 = 2MgO Calculations: Moles of Mg = the great crude / grinder plentitude = 0.35 / 24.3 = 1.44 x 10-2 groyne Moles of MgO = bunch / Molar potty = 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 practice for Magnesium oxide is MgO.

Magnesium Oxide Craville Studies Page 1 of 2 To come up the empirical formula using molar bunch of Magnesium oxide. 1 Strip of Mg ribbon Crucible and lid Pipe clay trian gle Tripod Matches Steel wool coat tongs Bu! nsen 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 plant 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 there is a larger percentage...If you want to get a full essay, rule it on our website: BestEssayCheap.com
