Percent Combustion of a Compound

Determining the Percent Combustion of a Compound utilisation: The consumption of this chemistry lab is to make a atomic number 12 oxide involved and determine the percent of burning at the stake it contains. Safety Notes: The burning milligram generates an intense white firing. entangled with the white light on that point is ultraviolet light as well. DO NOT smell at the magnesium as it is burning. DO NOT take on to puss the acid melting pot or crucible hats with your give! invariably use crucible tongs when handling in every(prenominal) toothsome 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, etna burner. Materials: 25cm of atomic number 12 ribbon Date turn off Item| sight in grams (g)| Magnesium Ribbon| 0.589| multitude of clean dry crucible and lid| 49.971| plug of crucible lid and confine BEFORE chemical reply| 50.561| pile of crucible lid and contents AFTER reaction| 50.943| bulk of magnesium oxide compound| 0.971| Calculations 1. Find the hole of the contents of the crucible. This is your brisk compound of magnesium. The mass of the magnesium oxide compound is 0.971. I got this say my subtracting the mass of the crucible lid and contents by and by the reaction with the mass of the crucible lid and contents subsequent 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. variety the constituent of magnesium in the compound. per centum of magnesi um = bunch 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 magnesium 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
