Why generate chemistry quiz questions from your own material

Ready-made lists of chemistry quiz questions are easy to find, but they rarely match the exact lectures, notation and lab terms your course uses. DeckOwl reads your own PDF, slides, DOCX file, plain-text notes or photos of pages and writes questions tied to that content, each with an explanation.

Multiple-choice, true/false and short-answer formats in one set
Explanations for correct and incorrect answers
Works with photos of handwritten or printed pages through text recognition

Example chemistry quiz questions on stoichiometry and reactions

What is the molar mass of CO2, using C = 12.01 g/mol and O = 16.00 g/mol?44.01 g/mol. Carbon contributes 12.01 and two oxygen atoms contribute 32.00, for a total of 44.01 g/mol.

True or false: increasing temperature usually increases the rate of a chemical reaction.True. Higher temperature gives molecules more kinetic energy, so more collisions exceed the activation energy.

Which type of bond holds the hydrogen and oxygen atoms together within a water molecule?Covalent bonds. Atoms share electrons within the molecule, while hydrogen bonds act between separate molecules.

What does Le Chatelier's principle predict when pressure is increased on a gas-phase system at equilibrium?The equilibrium shifts toward the side with fewer moles of gas, because that side lowers the pressure.

What is the pH of a 0.01 M HCl solution?2. HCl is a strong acid, so [H+] equals 0.01 M and pH = -log(0.01) = 2.

Generate the full set

Three question types

Multiple-choice, true/false and short-answer questions, each with an explanation of the correct answer.

Built from your material

Questions come from your lecture slides, readings or notes, so they cover the reactions, formulas and terms your instructor actually taught.

Export when you need it

Download as PDF or DOCX on the Plus plan. QTI 2.1 and Moodle XML export are available on Pro.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, text file or image of a page.

Frequently asked questions

How many chemistry quiz questions should I make for a unit test?

Create a set that covers every lesson in the unit, including definitions, formulas and reaction types. Mix multiple-choice and short-answer items so you practice both recognizing and recalling the material.

What makes a good chemistry quiz question?

A good question tests one concept at a time, such as balancing an equation, applying a formula or predicting a product. Explanations matter most because they show why each wrong choice is wrong.

Can I export generated quizzes?

PDF and DOCX export are included with the Plus plan at $39/year or $7.99/month. QTI 2.1 and Moodle XML export are included with the Pro plan at $14.99/month.

Is there a free way to try it?
