Lee and some other students working with Dr. Yung were conducting an experiment and ended up with some confusing results. In the experiment, each student combined sodium and hydrogen chloride, but, as shown in the table below, each student ended up with different results. Lee is trying to determine what happened.
In a few minutes, you will see a video of what happened when Lee combined two substances. Before you watch the video, see if you can predict why each student ended up with different results.
Student's nameStarting substancesEnding substances
Leesodium and hydrogen chloridehydrogen and sodium chloride
Verasodium and hydrogen chloridehydrogen, sodium chloride, and sodium
Domingosodium and hydrogen chloridehydrogen, sodium chloride, and hydrogen chloride
Why do you think Vera and Domingo ended up with three substances after the chemical reaction while Lee only ended up with two?
