Lab 16: Specific Heat of a Metal

Lab 16: Specific Heat of a Metal

Summary: 

In this lab, we identified a mystery metal by determining the specific heat and comparing it to the list of given specific heats. To find the specific heat of the metal, we put the metal in a beaker and put it on a hot plate. We had one cup of water in a styrofoam cup where we measured the initial temperature of which was 20°C. The second beaker of water on the hot plate was boiling at 95°C and when it reached 95°C we took it out and put it into the cold water. We then measured the final temperature of the water in the styrofoam cup after putting the heated metal piece into the styrofoam cup. We used calorimetry and water to determine the temperature change which is how the process worked since the heat lost by the hot metal is gained by the styrofoam cup of water. After collecting our data, we calculated heat gained, specific heat of the metal, and compared it to ehe table with he given specific heats. Although ours was quite off most likely due to miscalculations and lost heat due to certain factors, we were still able to determine what our mystery metal was.



Identification:

How we identified our mystery metal was using our data to finish filling out the data table above to help us with our calculations. We then calculated the specific heat by finding the heat gained by the water then the heat lost by the metal which equals the heat gained by the water. From that we compared our number which we calculated below, with the table given to us to find out that the metal was aluminum. 

Although our number was quite off, at the number 2560 J/kg °C that number was the closest to the number for aluminum which was 901 J/kg °C.

Lab 4: Atomic Mass of Candium

Image
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

Lab 21: Titration Lab

Lab 21: Titration Lab Set Up of the Lab  Analayte at equivalence (pale pink) Summary of Procedure: The first step to this lab was rinsing the burette with water and then with the base NaOH. After rinsing, we filled the burette with 0.25 NaOH up to the 0mL line using a funnel. For the first trial, we measured out 7.08 mL of vinegar which was our acid and 20 mL of water. We added it to our erelymer flask and 5 drops of the phenolphthalein acid. We put in our magnetic stirrer and put the flask on top of our hot plate and turned on the spinner to 160 RMPs which started the automatic mixing. We added the NaOH in slow increments. For the first try, we went a few drops over using 23.20 mL of the base. We did repeated the steps but with 7.02 mL of the vinegar (acid) and used 24.21 mL of the base and we slowly dropped in the NaOh until it reached a faint pink color when the analayte reached equivalence.  Data: Percent Ionization: [H3O+] / [CH3COOH] x 100 = 0.50%

Lab 14: Create a Smell Lab: Ester Synthesis

Lab 14: Create a Smell Lab: Ester Synthesis During this lab, we learned how a molecule can be changed into a different molecule using chemistry. We created different smells with acids like salicylic acid, acetic acid and sulfuric acid. Along with the acid's there were also alcohols that we used including isopentyl alcohol and methyl alcohol. We transformed the smells into esters by mixing certain alcohols with acids to create an initial smell and when put into the hot water it changed into an ester. 1. The odors of the first mixture before heating was a sharp, sour candy with a medicinal smell and after heating it was a sweeter smell of banana laffy taffy's with a hint of a nail polish smell. The odors of the second mixture before heating was a smelly vinegar and after heating it was an intense nail remover smell. The odors of the third mixture was a sweet/sour, sour patch kids candy smell and after heating it smelled like minty, wint o green lifesavers. They are differ
