How a chemistry quiz helps you study

A chemistry quiz works best when it tests the exact material in your course, so the questions match your lectures instead of a generic textbook. DeckOwl reads your notes or slides and writes questions on the topics you uploaded, including stoichiometry, bonding, equilibrium and acids and bases.

  • Multiple-choice, true/false and short answer questions from your own chemistry material
  • Explanations that show the reasoning behind each correct answer

  • Export to PDF, DOCX, QTI 2.1 or Moodle XML on paid plans
Example general chemistry quiz questions
What is the pH of a neutral aqueous solution at 25 °C?7. Pure water self-ionizes so that [H+] equals [OH-] at 1.0 × 10^-7 M, which gives a pH of 7.
Which type of bond forms when two nonmetal atoms share electrons?A covalent bond. Shared electron pairs hold the atoms together, unlike ionic bonds where electrons transfer from one atom to another.
True or false: increasing temperature always decreases the rate of a chemical reaction.False. Higher temperature usually speeds up a reaction because molecules collide more often and with more energy.
How many moles are in 58.44 g of NaCl (molar mass 58.44 g/mol)?1 mole. Moles equal mass divided by molar mass, so 58.44 g ÷ 58.44 g/mol = 1 mol.
What happens to an equilibrium system when its volume is reduced and pressure rises?The equilibrium shifts toward the side with fewer gas molecules, because that shift lowers the pressure, as Le Chatelier's principle predicts.

Built from your material

Questions come from the PDF, DOCX, PPTX, notes or page photos you upload, so the quiz matches what your instructor actually covered.

Three question types

Get multiple-choice, true/false and short answer questions in one quiz, mixed to test recall and reasoning.

Explanations on every answer

Each question shows why the correct answer is right, so a missed question becomes a lesson instead of a guess.

How it works

Upload your notes

Add a PDF, slides, a DOCX file, plain text or photos of pages. Photos are read with text recognition.

Choose the question types

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

Take the quiz and review

Answer in the browser, read the explanations and retry the questions you missed.

Quizzing yourself before an exam shows which concepts you can already explain and which need another pass. Use the explanation after each answer to find the reasoning behind a mistake, not just the correct letter.

Frequently asked questions

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

Ten to fifteen questions usually cover the main ideas of a chapter well, with a mix of multiple choice and true/false. Start with fewer if the topic is new and add more as you get comfortable.

What should I do after I miss a chemistry quiz question?

Read the explanation, then restate the correct reasoning in your own words before moving on. Retry missed questions a few days later so the concept sticks.

Can I export my chemistry quiz?

Exports are paid features. PDF and DOCX come with Plus at $39/year or $7.99/month, and QTI 2.1 and Moodle XML come with Pro at $14.99/month. The free plan includes 3 generations per month and study in the browser.

Do I need a credit card to try it?

No. You can start on the free plan without a credit card, and students get 40% off with a school email.
