A nalyzing Data In the laboratory, a sample of pure nickel
Chapter 7, Problem 7.1.71(choose chapter or problem)
A nalyzing Data In the laboratory, a sample of pure nickel was placed in a clean, dry, weighed crucible. The crucible was heated so that the nickel would react with the oxygen in the air. After the reaction appeared complete, the crucible was allowed to cool and the mass was determined. The crucible was reheated and allowed to cool. Its mass was then determined again to be certain that the reaction was complete. The following data were collected: Mass of crucible = 30.02 g Mass of nickel and crucible = 31.07 g Mass of nickel oxide and crucible = 31.36 g Determine the following information based on the data given above: Mass of nickel = Mass of nickel oxide = Mass of oxygen = Based on your calculations, what is the empirical formula for the nickel oxide?
