1. Why do we want a reaction to go to completion? 2. In general, what are the most reactive parts of a molecule? 3. Which TLC plate shows a completed reaction? SM = Starting Material, RXN = Reaction, P= Product Why do we want a reaction to go to completion?! Consuming all the starting material means less waste Consuming all the starting material means you don't have to separate the starting material from your product o Consuming all the starting...
1. A reaction was conducted in 1-butanol at -80 ˚C and took 72 hours to go to completion. How long would you expect it to take if the reaction were run at 0 ˚C? How long would you expect it to take if the reaction were run at 100 ˚C? When the reaction is ran at 0 ˚C, it selectively forms one isomer over the other by a ratio of 100:1. What does that say about the different energies of...

Question Completion Status: QUESTION 5 What was the observed temperature change during the reaction time? [2 pt] O it increased O it decreased O it remained unchanged QUESTION 6 Why did the temperature change or not change during the reaction? [2 pt)
Go and “Google” yourself and see what information is available on you. How much did you find? Was it more or less than what you expected or were there some surprises? Is there any inaccurate or unauthorized information? If hypothetically you found some information returned by your search that you wanted to remove, how would you go about doing that? Explain
Name Lab Partner LAB 9 REFLECTIVE EXERCISES Lab Section 1 What data did you collect to indicate that you successfully produced aspirin? What did your results indicate about the purity of the aspirin you obtained? Explain your answers. 2 Given that the melting point of salicylic acid is 159 C, can you be certain that the product you isolated was not pure solicylic acid that was unchanged during the reaction? Can you be certain that the product you isolated was...

C. When exposed to oxygen, fructose undergoes combustion. If you run the reaction with 10.0 g of fructose and 10.0 g of oxygen, how many moles of CO2 can you produce? The unbalanced equation for this reaction is: CeH12O6 + O2 → CO2 + H2O d. You run the reaction in lab and produce 9.49 g of CO,. Did the reaction go to completion? If not, what is your percent yield?
