Unformatted text preview: evaportated. My compound x weighed about .33460 g. Part C, I added the 2mL water to the solid that had remained in my testtube. After centrifuging the testube three times I was able to gather most of the deccante into the crucible. This component Y in my lab weighed about .22430 g. My sources of error began in the next step which was to heat the crucible containing compound Y. When the Bunsen burner was being lit, the crucible accidently fell off the iron triangle and so some of the component was lost. In part D, I had to heat the solid compoent Z, and I may have put the text tube too close to the flame, allowing my final component to decompose because when I weighed it I only got .02999g which was not a significant amount. After I completed the lab I calculated the percnatge of each compoent getting 49.514% for component X, 32.042% for compenent Y and less than 5% for compoenet Z. Compentents X and Y added together was 81.56%, showing that Z should have been about 18.44%....
