How a chemistry LC quiz helps you revise

Leaving Cert chemistry rewards students who can apply reactions and calculations, not just recall definitions, so a chemistry LC quiz is most useful when it asks you to use what you have learned. Short, frequent tests on mole calculations, equilibrium and bonding show you where your understanding is thin before the exam does.

Example Leaving Cert chemistry quiz questions

What is the pH of a solution where the hydrogen ion concentration is 1 × 10^-3 mol/L?pH = 3. The pH scale is the negative logarithm of the hydrogen ion concentration, so -log(10^-3) = 3.

True or false: raising the temperature of a reaction increases its rate.True. Higher temperature gives particles more energy, so a greater fraction of collisions meet or exceed the activation energy.

What is the electron configuration of chlorine (atomic number 17)?1s2 2s2 2p6 3s2 3p5. Chlorine has 17 electrons, and the 3p subshell holds the last five.

Why does ethanol have a higher boiling point than ethane?Ethanol molecules form hydrogen bonds with each other, which take more energy to break than the weak van der Waals forces between ethane molecules.

In the equilibrium N2 + 3H2 ⇌ 2NH3, which way does the position shift when more N2 is added?To the right, toward NH3. The system consumes some of the added nitrogen to partly offset the change.

Questions from your material

Each quiz is drawn from the PDFs, slides, DOCX files or photos of pages you upload, so it matches your class and your syllabus notes.

Three question types

Mix multiple choice, true/false and short-answer questions in one quiz to check recall and reasoning.

Explanations for every answer

After each question you see why the correct answer is right, which helps with the ones you missed.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of your chemistry pages.

Choose a quiz format

Pick multiple choice, true/false or short answer, or combine them.

Take the quiz and review

Answer in the browser, read the explanations, then go back to the topics you missed.

Ready-made quizzes rarely match the topics your teacher emphasized. DeckOwl builds a quiz from your own material, so the questions follow your notes and your class order. Start with a small quiz on one unit, then mix units once you are comfortable.

Use the explanations as part of the study session. When you miss a question, write the correct reasoning in your own words and test yourself on it again a day later.

Frequently asked questions

How many questions should I do in one chemistry LC quiz session?

Ten to fifteen questions on a single topic is a good session length for most students. Shorter, focused sessions are easier to repeat across the week than one long test.

Which chemistry topics work best for quiz practice?

Topics with clear rules, such as mole calculations, reaction rates, equilibrium and acid-base pH, suit quiz questions well. Short-answer questions are better for explaining reasoning, such as why a reaction shifts after a change in conditions.

Can I export my quiz?

The free plan lets you study in the browser without exports. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML export.

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 Plus with a school email.
