Penny Lab
In this lab, my lab partner and I sawed a hole in the side of a penny in order to expose the inner zinc core beneath the copper. We then extracted said zinc by placing the penny into hydrochloric acid to dissolve it. Through this, we were able to see that hydrochloric acid can dissolve zinc. We were able to determine what percent of our penny was copper and what percent was zinc. |

Molar Volume Lab
Through this lab, we tested our knowledge of gas laws in a lab environment. We balanced a chemical equation. Afterwards, we determined the amount of hydrogen that would be produced through the reaction of Magnesium and Hydrochloric acid by using the ideal gas law. We placed a strip of magnesium into a tube and added 10 mL of HCl, and then filled it to the rest with water. We added the magnesium, and then inverted it so that the HCl could react with the Mg. |
