Chemistry 9-27-11 Law of Conservation of Mass Lab

CHEMISTRY – Great job on the lab today. So did you see the Law of Conservation of Mass today? Why not? What are you going to do differently in the lab tomorrow, and why do you think it will work? Here’s the the format for Part 1 and 2 of the lab write up, just in case you didn’t get it in class today: CONSERVATION OF MASS Lab Report. Don’t forget – short classes tomorrow, so you need to come to class moving quick like a bunny!

  1. For the extension question #2 we have to design a procedure to observe the law of conservation of mass with a burning log. how can you burn something and keep all the gases and smoke contained if it needs oxygen to burn?

    • If the container had enough oxygen, you might be able to ignite the flame long enough to burn the log for a little while. A short amount of time should be enough to prove the theory.

      BTW: Good thinking. I didn’t even think about this.

  2. I enjoyed the lab that we did this week! Doing it the second time was a lot better than the first. It helped me understand a lot about the Law of Conservation of Mass. Todays class was great, too by the way ๐Ÿ™‚

  3. in the second lab we did it was so weird how if you waited to long the mass would decrease but we finally got it thank you ms skinner!
