Unformatted text preview: Mass (g) 1.69 .31 % Mass 85 15 Moles .027 .019 This reaction is a Copper (II) and oxygen reaction, I found this out by finding the mole ration between my measurements in the lab. There were plenty of occasions where discrepancies could have occurred. I know that not all the copper oxide was reduced into just copper, leaving more oxygen atoms in the substance. The tube I had, had a small leak so the complete reaction could not take place. Reducing agent- is the element or compound in a redox reaction that reduces another species, in this case methane gas Smelting- to fuse or melt (ore) in order to separate the metal contained. in this case the process of reducing copper oxide into copper. Reduction- A reaction in which oxygen is removed from a compound. Percent composition- a relative measure of the mass of each different element present in the compound. Empirical formula- a simple expression of the relative numbers of each type of atom in it....
