101 Chemistry Trivia Questions To Reveal if You Belong in the Lab

Human civilization would be nowhere without chemistry. Of course, it’s literally true that we’d just be a mass of ooze if it weren’t for the chemical reactions that created life, but the science of chemistry is pretty important too. As a result, you’re basically doing your duty as an organic life form by answering these chemistry trivia questions and answers.

If you’re concerned that only lab scientists are chemistry experts, think again. Besides creating the fodder for science fair volcanoes, chemistry also offers the building blocks of medicine, construction, neuropsychology, and even photography. 

On top of that, there’s a rich history behind chemistry, dotted with such figures as Alfred Nobel, Marie Curie, and Rosalind Franklin. That means that whether you’ve memorized the Periodic Table or not, you know more about chemistry than you think.

Even when you’re done with the chemistry trivia quiz, there’s still room for your mind to expand. Try out these quizzes on math, physics questions, nature quiz and science trivia questions.
