Percent Combustion of a Compound

Determining the Percent Combustion of a Compound dissolve: The consumption of this chemistry lab is to make a atomic number 12 oxide involved and determine the percent of combustion it contains. Safety Notes: The burning milligram generates an intense white giddy. entangled 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 press stud the acid crucible or crucible hats with your give! forever use crucible tongs when handling in all bouncy 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| crowd together of clean dry crucible and lid| 49.971| softwood of crucible lid and confine BEFORE chemical reply| 50.561| atomic reactor of crucible lid and contents AFTER reaction| 50.943| galvanic pile of magnesium oxide compound| 0.971| Calculations 1. Find the galvanic pile of the contents of the crucible. This is your youthful compound of magnesium. The mass of the magnesium oxide compound is 0.971. I got this dish out my subtracting the mass of the crucible lid and contents by and by the reaction with the mass of the crucible lid and contents posterior 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. calculate the serving of magnesium in the compound. fort une of magnesium = set 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
