Chemical Reaction Quizzes Online & Trivia

A comprehensive database of more than 49 chemical reaction quizzes online, test your knowledge with chemical reaction quiz questions. Our online chemical reaction trivia quizzes can be adapted to suit your requirements for taking some of the top chemical reaction quizzes.

Chemical reactions are part of our daily lives. From cooking in the kitchen, to driving a car, these reactions are commonplace. In a chemical reaction, the molecules of one substance break apart and join together with those of another substance to create a different compound (combination of molecules).

Many chemical reactions are non-reversible changes .You cannot turn a baked cake back into its raw ingredients. Some chemical reactions can be reversed, and re-formed into the original substances. These are reversible changes.

If you fancy one reaction or another, then you will most surely enjoy the questions of these quizzes: “The smallest particle of gold which still retains its characteristics is?”, “An atom containing 19 protons, 20 neutrons, and 19 electrons has a mass number of?”, and “What does all matter have?”.
