The purpose of the reactions lab was to test the effect of solid elements over liquid or aqueous compounds or to see the effect of what certain elements can do to others.

Favorite Reaction
Although I was unable to personally experience the reactions, I did watch some on youtube and my favorite one was the magnesium metal ribbon reacting with oxygen to create the ultraviolet light.
Lab 12: Electron Configuration Battleship When you lose... Biggest Challenge The biggest challenge while playing the electron configuration battleship was figuring out where she placed her ships on the periodic table and guessing strategically where they were. Along with that, the pronunciation of certain elements. Learned Some things that I learned while playing the electron configuration battleship was how to quickly read the electron configuration as I played as well as a better understanding of it. I also learned a new, different way of playing battleship with the periodic table and the electron configuration.
Lab 15: Evaporation and Intermolecular Attractions Purpose: In this lab, we had five different substances that we measured the difference in temperature before anf after letting the liquid evaporate for four minutes. The purpose of this lab was to figure out the strongest intermolecular bond out of the five substances. Pre Lab Table: Lab Data: Questions: 2. The difference that Methanol had was -15 °C, Ethanol at -9.3 °C, n-Butanol with -3 °C, Glycerin at 3.7 °C and lastly Water at -3.4 °C. Between all five of the substances, the one with the biggest difference was Methanol with -15 °C which also shows has the weakest bond. While Glycerin with 3.7 °C has the strongest bond. The differences in the initial temperature and final temperature helps us understand the strength of the bond. This is because where there is a higher difference, there is a weaker bond and with a smaller difference there is a stronger bond. The differences in temperature for...
Atomic Mass of Candium Purpose: The purpose of this lab was to find the average atomic mass of the element candium. To test this we used three candium isotopes being, M&M's, Pretzel M&M's and Skittles. Average Atomic Mass: .77 amus Conclusions: 1. Ask a group nearby what their average atomic mass was. Why would your average atomic mass be different than theirs? Another groups average atomic mass was 1.0 amus. Our average would be different than others because the variations of the isotopes and weight was different for each group. 2. If larger samples of candium were used, for example if I gave you a whole backpack filled with candium, would the differences between your average atomic mass and others' average atomic masses be bigger or smaller? Defend your answer. The average atomic masses would be smaller because there would be more amounts of candium meaning a larger amount to divide among and the weight of the outliers would round out. 3. If you took any ...
