Designing a Hand Warmer By: Devon Atchison, Tyler Pennington, and Vicki Smith Observations Immediately after putting in the Lithium Chloride, a steam or a white powder arising from the solution was observed. Also, when putting the solutions into the water, the stir rod stopped.
Hand warmer challenge: Home Introduction Procedure Results Discussion Conclusion Bibliography and Acknowledgments looking at the results we saw which chemicals created more amount of heat when its being applied to water and salt. In the experiment we used three types of Chemicals: CaCl2 (Calcium Chloride), MgSO4 ( Magnesium Sulfate), and LiCl ( Lithium Chloride). We calculated the different.
CONCLUSION: After performing this lab we conclude that our experiment was a success. Even though we had some errors during our experiment for example we used ounces instead of grams we figured out a way to fix our experiment.
