Why generate your own general chemistry quiz questions

Ready-made general chemistry quiz questions with answers are easy to find online, but they rarely match the chapters, notation or problem style in your course. A question on stoichiometry from a generic bank may not use the same units or reaction types your instructor tests.

Match questions to your own syllabus instead of a generic question bank.
Read the explanation for every answer, including the ones you got right.
Redo missed stoichiometry and equilibrium questions after a day to check retention.
Use short-answer questions to practice writing out full working, not just picking an option.

Example general chemistry quiz questions with answers

What is the molar mass of water (H2O), using 1.008 g/mol for H and 16.00 g/mol for O?18.02 g/mol. Water has two hydrogen atoms (2 × 1.008 = 2.016) and one oxygen atom (16.00), so the sum is 18.02 g/mol.

True or false: For most solid solutes, increasing the temperature increases solubility in water.True. Dissolving most solids in water is endothermic, so higher temperature generally shifts equilibrium toward more dissolved solute.

Which quantum number determines the shape of an orbital?The azimuthal (angular momentum) quantum number, l. It sets the subshell shape, so s orbitals are spherical and p orbitals are dumbbell-shaped.

What is the pH of a 0.001 M HCl solution?pH 3. HCl is a strong acid that fully dissociates, so [H+] = 1.0 × 10^-3 M and pH = -log(1.0 × 10^-3) = 3.

In 2H2 + O2 → 2H2O, how many moles of water form from 4 moles of H2?4 moles. The equation shows a 2:2 mole ratio between H2 and H2O, so 4 moles of H2 produce 4 moles of H2O.

Pick the question type that fits your exam. Each question comes with a correct answer and a short explanation.

Built from your own material

Questions follow your lecture slides and textbook chapters, so you practice what your course actually covers.

Study in the browser

Answer questions online for free. Export to PDF, DOCX or a learning platform when you upgrade.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of a page. Photos are read with text recognition.

Choose the question type

Select multiple choice, true/false or short answer. Each question includes an explanation of the answer.

Practice and review

Work through the quiz, check each answer against its explanation, and return to missed questions.

Generating questions from your own lecture slides or notes keeps the practice aligned with the exam. Each question includes an explanation, so you can see why an answer is right and where your reasoning went wrong.

Start with the units you find hardest, such as equilibrium or electron configuration. Answer without looking at the notes first, then read the explanation for every question you missed.

Frequently asked questions

How many practice questions should I do for general chemistry?

There is no fixed number. A useful set covers every key idea in a unit, and you should keep practicing until you can explain each answer without looking at the notes.

How can I check whether a general chemistry answer is correct?

Check the units and significant figures first, then compare your steps with the explanation. If your final value differs, look for a sign error, a missed coefficient in the balanced equation or an incorrect molar mass.

Does the free plan let me export my quiz?

No. The free plan lets you study in the browser, with 3 generations per month. PDF and DOCX export are available on Plus, and QTI 2.1 and Moodle XML export are available on Pro.

Can I export quiz questions to a learning platform?

Yes, on the Pro plan. QTI 2.1 and Moodle XML exports let you import questions into platforms that support those formats.
