1. Do the experimental results support or disprove your hypothesis? Explain your answer.
2. Do the collection temperatures, ignition results and density values for each fraction
correspond with the probable composition of the distillate in each flask? Explain your
answer.
3. Provide the balanced chemical equation for the reaction that occurred in each positive
ignition test. Is this a chemical change or a physical change? Give a chemical property of
this reaction.
