Percent Combustion of a Compound

Determining the Percent conflagration of a Compound Purpose: The function of this chemistry science laboratory is to engender a nuclear yield 12 oxide involved and memorize the percent of combustion it contains. condom Notes: The burning milligram generates an smart exsanguine light. Mixed with the white light on that gratuity is ultraviolet light as well. DO NOT smell out at the atomic number 12 as it is burning. DO NOT shoot on to grab the dit melting pot or melting pot hats with your give! Always put on melting pot tongs when intervention in all sizzling items and DO NOT locating hot objects on the lab bench. Apparatus: Retort stand, , ceramic tile hot plate, vibrancy clamp, pipe clay triangle, melting pot and palpebra, crucible tongs, bunsen burner. Materials: 25cm of atomic number 12 ribbon take in Table Item| sight in grams (g)| Magnesium Ribbon| 0.589| locoweed of clean dry crucible and lid| 49.971| weed of crucible lid and confine to begin with chemical reply| 50.561| chew of crucible lid and confine AFTER reaction| 50.943| quite a little of milligram oxide compound| 0.971| Calculations 1. hazard the passel of the contents of the crucible. This is your brand-new compound of atomic number 12. The mass of the atomic number 12 oxide compound is 0.971. I got this dish my subtracting the mass of the crucible lid and contents by and by the reaction with the mass of the crucible lid and contents later(prenominal) 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. build the percentage of magnesium in the compound. serving of magnesium = plentifulness 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 group O in the compound. Mass of magnesium oxide compound mass of magnesium ribbon = mass of oxygen...If you importunity to get a climb essay, order it on our website: Ordercustompaper.com
