Lab 1: Airbag Lab
For the airbag lab, we wanted to use Stoichiometry to create the ideal airbag. Fist, we added 2.5 mL of vinegar to a zip lock bag. After, we added 2.53 grams of baking soda to the bag then closed it and had the teacher check to see how inflated it was. After the lab, i was more comfortable with using Stoichiometry and i realized that the chemical reaction that took place caused the baking soda to dissolve, leaving only vinegar and water in the bag. I also learned that airbags in cars and the airbags in the lab are both similar because they are not inflated from compressed gas, but rather from the products of a chemical reaction. Our results were very consistent with what we should have gotten, but we did not shut the bag fast enough, therefore the air was able to escape.

Lab 2: The Iron-Copper Molar Tango: A single replacement reaction
For this lab, the purpose was to calculate the mass and number of moles of copper produced and the number of moles of iron that reacted. We also had to determine the molar relationship between iron and copper. First, we weighed a dry 150 mL beaker and recorded that it was 91.08 grams. Then we measured the mass of CuSO4 put in the beaker and recorded that it was 103.07 grams. We then found the mass of the steel wool and mass of filter paper all by itself and lastly, we found the mass of the filter paper and dried copper which was 4.43 grams. After the lab, i learned that the equation listed had a mole ratio of 1:1 and that by using the mole ratio, i could find the mass of the copper (22.2 grams).
