Chemical Reaction Quizzes

Chemical Reaction Quizzes & Trivia
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?”.
