Why build your chemistry quiz from your own course material

If you want a ready-made chemistry quiz to play as a class game, the most useful version is one that matches your syllabus. DeckOwl reads your own chapter or slides and writes questions about the terms, reactions and worked problems your course actually covers.

  • Questions generated only from the notes or slides you upload
  • Multiple choice, true/false and short answer formats
  • Explanations that show the chemistry behind each answer
  • Export options for PDF, DOCX, Anki and LMS formats on paid plans
Example chemistry quiz questions with answers
What is the molar mass of water (H2O) to one decimal place?18.0 g/mol. Add 2 × 1.0 for hydrogen and 16.0 for oxygen.
True or false: increasing temperature usually increases the rate of a chemical reaction.True. Higher temperature gives molecules more kinetic energy, so more collisions reach the activation energy.
Which type of bond forms when atoms share electrons?A covalent bond. Sharing lets both atoms fill their outer shells, unlike ionic bonds where electrons transfer.
What is the pH of a solution with [H+] = 1 × 10^-3 M?pH 3. pH is the negative log of the hydrogen ion concentration, and −log(10^-3) equals 3.
Balance H2 + O2 → H2O. What coefficient goes in front of H2O?2. Two H2O molecules contain four H atoms and two O atoms, giving 2 H2 + O2 → 2 H2O.

Multiple choice, true/false and short answer

Each chemistry quiz mixes question types so you practice recall, recognition and written explanation.

Explanations for every answer

Wrong answers show why the correct option works, so you learn the reasoning behind reactions, formulas and bonding.

Built from your own material

Questions come from your PDFs, DOCX or PPTX files, plain notes, or text read from page photos, not a generic question bank.

How it works

Upload your material

Add a PDF, DOCX, PPTX, text notes or photos of the pages from your chemistry course.

Choose your question types

Pick multiple choice, true/false or short answer, then generate the quiz.

Study and retake

Work through the quiz in your browser, read the explanations, and retake the questions you missed.

Each question comes with an explanation, which matters in chemistry because a wrong answer often hides a unit mistake, a balancing error or a misread bond type. Reading why the correct option is right helps you fix the step that went wrong.

Exports to PDF, DOCX and Anki are part of the Plus plan, and QTI 2.1 and Moodle XML export are on Pro, so you can move a quiz into a learning system your school uses.

Frequently asked questions

How many questions should a chemistry quiz cover for one chapter?

Start with one question for each key term, formula or reaction in the chapter, then add questions on the worked examples so you practice applying them. Adding a few harder questions near the end helps check whether you can combine ideas.

What makes a good chemistry quiz question?

A good question tests one idea, such as balancing an equation, identifying a bond type or converting units, and has distractors that reflect common mistakes. Explanations should name the rule used so you can apply it to new problems.

Can I export a chemistry quiz?

Exports to PDF, DOCX, Anki and CSV are paid features, with unlimited generations on Plus. QTI 2.1 and Moodle XML export are available on the Pro plan.

Is it free to try?

Yes. The free plan includes 3 generations per month and studying in the browser, and you do not need a credit card to start.
