Length of time the Hot Water Fizzed Length of Time the Cold Water Fizzed Test 1 Test 2 Data Table Lab Report: Reaction Rates and Temperature Laboratory Materials:
•4 antacid tablets
•2 clear cups labeled Hot and Cold
•Timing Device Hypothesis: Procedure:
•Observe the experiment in the virtual lab window. Conclusion: 1)What evidence indicates that a chemical reaction took place?
- The evidence that indicates a chemical reaction took place was when the antacid tablets dissolves into the cups of water.

2)Was your hypothesis correct? Support your answer with data from your experiment.
- My hypothesis was correct because as you can see from the data table the antacid tablet in the hot water took less time to dissolve then the antacid tablet in the cold water.

3)Predict what would happen if we conducted the same experiment with room temperature water.
- What I think would happen if i conducted the same experiment wit room temperature water is it'll result in the same act as if i was to put it in the hot water just maybe not as fast. 41 seconds 1 minute 9 seconds 51 seconds 1 minute 10 seconds If you put antacid tablet into hot water,then it'll dissolve faster than in cold water.
