Chem 2- Lab. #28 Part II Data

For my Chemistry 2 Class:

Here is the data for Part II of Lab. #28:

Test Tube 1: Reaction time = 1500 sec.
Test Tube 2: Reaction time = 1800 sec.
Test Tube 3: Reaction time = 1200 sec.

For rolled Mg strip, the piece stays near the bottom of the test tube at all time.
For flat piece of Mg strip, it flows up and down between the surface and the mid-height of the tube solution.

You should be able to complete the Lab. Report base on your Part I and this Part II data.
