Copper was mixed with nitric acid (HNO3). Fizzing and bubbling occurred along with a color change from colorless to blue. The gaseous product was collected in a test tube and exposed to a glowing splint. A loud pop was heard. (WCSU24) Identify the gas produced and indicate what observation would correspond to a different gas by making the following matches.

(WCSU24) Edit the abstract below by selecting the sentences that should be kept in the final draft. Single replacement reactions occur when a single element reacts and takes the place of another element in a compound. I learned about stoichiometry when I did this experiment. Herein, the synthesis of copper from aluminum and copper(II) sulfate is described. 5.0 g of aluminum were added to 50 mL of copper(II) sulfate. Once the chemical reaction was balanced, I was able to determine the amount of moles of each reactant used when undergoing the reaction to produce copper. The mass of copper isolated was 2.0 g giving a yield of 48%. This lab was super fun!
