Experiment 1: Synthesize Copper Oxide from Copper1.Took a crucible, balance, and bunsen burner2.Placed the crucible to the balance to record its mass3.The Mass of the crucible: 35.000g4.Moved the crucible back to the workbench 5.Add 10g of copper to the crucible6.Put the crucible back to the balance and measure its mass with the copper added7.The mass of the crucible + copper: 45.000g8.Move the crucible to the bunsen burner and recorded the initial color of the contents9.The initial color of the contents: bronze, red-orange, light brown10. Turned on the bunsen burner to low flame11. Heated until the reaction is complete12. Observation of the reaction: color changed to black13. Moved the crucible back to the workbench and turned off the bunsen burner14. After cooling off, weighed the crucible plus its contents15. The total mass of the crucible + contents: 47.518g16.
