Lab 10: Mole to Mass Relationships Lab

I. Introduction:
The purpose of this lab was to obtain a theoretical yield and percent yield by using mass to mass and mass to mole stoichometry. We investigated the relationships in the reaction which consisted of sodium bicarbonate and hydrochloric acid. This reaction yielded salt, carbon dioxide, and water after it was heated. Lastly the salt was measured and used to calculate our data.

II. Data:



III. Questions 1-4:



IV: Error/Problems: Our percent error was over 100 percent because we left the reaction heated for too long. This allowed the solid to accumulate more and therefore gaining more mass than the theoretical yield mass. Also, our measurements might not have been precise enough and we took too much acid or baking soda. This could have also increased our mass greatly. 

V: Product after Heating:

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. There are many instances where an experimental error may have occurred  For exam

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.
