Didn’t Zinc That One Through

| QC, Canada | Learning | July 2, 2015

(In my high school chemistry class, there was a very enthusiastic blonde girl that, well, lived up to the stereotype. This day, in the lab, we burned up some copper powder over a flame and were comparing the weight before and after the experiment.)

Teacher: “So, in order to gain mass, the copper had to bond with some other element present in air in order to form copper oxide. Any ideas?”

Blonde Girl: “Oh, I know! It’s zinc!”
