Chemical Reactions Quiz

Chemical Reactions Quiz takes a cue from history, specifically, when Antoine Lavoisier helped establish the Law of Conservation of Mass by carefully measuring what went in and out of chemical reactions. His meticulous experiments in the 18th century gave structure to the idea that nothing is lost, just changed. That core idea is behind nearly every reaction you’ll come across in this quiz. This isn’t just about balancing equations or memorizing names. It’s about spotting patterns, understanding results, and thinking like early chemists who turned curiosity into science. Explore different types of chemical reactions, from simple changes to gas-releasing transformations. No lab coats needed here just a willingness to think like a scientist for a few minutes.
