Assignment #2

1) What are three topics that we discussed in class today?
-Three topics that we discussed today are the Periodic Table, chemical reactions, and the macroscopic world.

2) What did you find interesting in class today?
-Today in class what I found most interesting is the experiment you did with the balloons. I knew that a balloon filled with air would pop when lit by a match but I did not know it would make such a loud noise when filled with H20 gas.

3) List a few ways that we identify that a chemical reaction has occurred.
-If it changes color
-If it changes from a liquid to a solid of vise-versa
-If it gives off heat
-If there is some sort of smell or sound

4)Write a question or a comment that you have about the material we covered today.
-Why exactly did the balloon not make such a loud noise when filled with only hydrogen or only oxygen?
