Quiz and Experiment

Today we began class with a short little quiz on writing and naming formulas which we were working on for the past week. The quiz also included balancing equations from last week.

We then moved into an experiment called the Rate of Reactions. It included an Alka-Seltzer tablet, different water temperatures(cold, medium and hot), film canister, beaker(cup) and a graduated cylinder. The goal was to determine if different water temperatures or surface area of the tablet effected how fast the lid exploded off. We recorded our observations in a chart, and were asked questions such as the effect the water temperature and volume had on the experiment. Our group determined that the quickest reaction occurred when there was a high level of hot water and when the tablet was in one piece(not crushed). The only trail that did not produce a result was the cold water.
