Percent Combustion of a Compound

Determining the Percent Combustion of a Compound manipulation: The consumption of this chemistry lab is to make a nuclear number 12 oxide involved and determine the percent of conflagration it contains. Safety Notes: The burning milligram generates an intense white start out. abstruse with the white light on that point is ultraviolet light as well. DO NOT smell at the milligram as it is burning. DO NOT take on to crack the acid crucible or crucible hats with your give! continuously use crucible tongs when handling in all(prenominal) calefacient items and DO NOT place hot objects on the lab bench. Apparatus: Retort stand, , ceramic tile hot plate, ring clamp, pipe clay triangle, crucible and lid, crucible tongs, bunsen burner burner. Materials: 25cm of atomic number 12 ribbon Date dodge Item| sight in grams (g)| Magnesium Ribbon| 0.589| down of clean dry crucible and lid| 49.971| bus of crucible lid and confine BEFORE chemical rep ly| 50.561| pack of crucible lid and contents AFTER reaction| 50.943| surge of magnesium oxide compound| 0.971| Calculations 1. Find the aggregated of the contents of the crucible. This is your parvenue compound of magnesium. The mass of the magnesium oxide compound is 0.971. I got this behave my subtracting the mass of the crucible lid and contents by and by the reaction with the mass of the crucible lid and contents afterwards the reaction, which equals 0.382. Then I added 0.382 to the mass of magnesium ribbon, which is 0.589 to get 0.971. 50.943- 50.561 = 0.382 0.382 + 0.589 = 0.971 2. configuration the dowery of magnesium in the compound. fortune of magnesium = sight of magnesium ribbon x100 Mass of magnesium oxide compound Percentage of magnesium = 0.589 x100 0.971 Percentage of magnesium = 0.60659 x100 Percentage of magnesium = 60.66 The percentage of mag nesium is 60.66%. 3. Find the percentage! of oxygen in the compound. Mass of magnesium oxide compound mass of magnesium ribbon = mass of oxygen...If you urgency to get a full essay, order it on our website: OrderEssay.net
