1.) A match must be struck against an object to produce a spark to start the burning process. Once the match starts burning, it releases a large amount of energy. Describe, in detail, what the potential energy diagram would look like for the burning of a match, and explain how each part of the diagram relates to the process described above.
2.Describe the chemical combination that you investigated in the hands-on lab activity. Also describe any observations from the investigation, including the temperature change of the container.

1) The plot would look like this: It would be a concave down curve going up, representing the activation energy, then a downward concave down curve that will end below the original starting point. This means that the reaction was exothermic, since Delta H is negative.
2) I can't really answer this... I wasn't there to observe the direct results you did. But I would predict that the temperature of the surroundings first decreased SLIGHTLY, almost negligibly, representing the activation energy, then the temperature dramatically increased in comparison.
