Lab 8: Mole Baggie Lab

Summary:  The purpose of this lab was to determine the unknown substance inside of a plastic bag using only the information given and mole conversion formulas. For Set A and B bags, the mass of baggie was written on the outside, as well as either the number of moles or number of particles. For the A5 bag, we weighed the whole bag and then subtracted the mass of the empty bag to find the weight of the substance. Then, we calculated the molar mass by dividing number of grams by number of moles. Finally we compared it with the molar mass of the other possible compounds and decided which matched the closest. We did the same for the B3 bag, but we were given the number of particles instead of of the moles. We found out the of moles, by using a formula and then sued the molar mass formula to find the final answer.

Conclusion: The bags we had were A5 and B3. A5 had the identity of Zinc Oxide. B3 had an identity of Potassium Sulfate.

Lab 18: Alka Seltzer and the Ideal Gas Law

Image
I. Introduction:   In this lab the purpose was to measure the reaction between Alka Seltzer and water and to  determine the mass of the gas produced. What we did was, first we smashed up an alka seltzer tablet and put it inside a balloon. We then put the balloon over a graduated cylinder full of water and as the two substances combined, CO2 was produced and collected in the balloon. After all the gas had been created we measured the circumference of the balloon. We then emptied the gas and refilled the balloon with water until it had the same circumference. From this we were able to measure the water and find the volume. Through a series of calculations , we were able to conclude that the mass of CO2 was around 1.26 grams in our experiment. II. Data:  III. Calculations:  (Setup) IV: Analysis Questions:  1. Discuss an area in this lab where experimental error may have occurred.

Lab 11: Flame Test Lab

Image
I. Introduction:  The purpose of this lab was to observe how certain atoms react and release energy within different compounds and solutions. We performed the lab by taking samples of the nine compounds and held them over a bunsen burner. Then, we observed any color or texture changes and recorded them. We also had identify two unknown chlorine compounds using flame tests. To identify the two unknowns, we compared their flame colors to those of the other eight compounds and assumed the solution based of this. II. Pre Lab Questions: III. Data:  IV. Analysis Questions:  Picture of LiCl emitting Pink Light:

Lab 12: Electron Configuration Battleship

Image
I. Picture of My Setup:  II. Biggest Challenge: My biggest challenge playing was trying to do the electron configurations in my head. Also trying to solve the f block configuration in my head was extremely challenging. III. What I Learned: I learned how to solve electron configuration faster and efficiently using the periodic table.
