Why build your own chemical reactions flashcards

If you are searching for a printable set, a generic deck rarely matches the reactions and notation your course uses, so chemical reactions flashcards made from your own material are the more useful starting point.

Cards cover reaction types, reactants and products, and balancing steps from your source
Balanced equations with coefficients go on the back so you can check your work
Spaced repetition keeps older reactions in rotation until you can recall them quickly
Free plan includes 3 generations per month for studying in the browser

Example chemical reactions flashcards

What type of reaction is A + B → AB?A synthesis (combination) reaction, where two or more reactants combine into one product.

What is a decomposition reaction?A single reactant breaks down into two or more simpler substances, such as hydrogen peroxide breaking down into water and oxygen.

What is an exothermic reaction?A reaction that releases energy to the surroundings, usually as heat, so the products have less energy than the reactants.

What does the law of conservation of mass state for chemical reactions?Matter is neither created nor destroyed, so the total mass of the reactants equals the total mass of the products and every atom must be accounted for.

What is a combustion reaction?A substance reacts rapidly with oxygen, usually releasing heat and light, and when a hydrocarbon burns it typically produces carbon dioxide and water.

Generate the full set

Built from your material

Upload a PDF, slides, a DOCX, plain notes or a photo of a page, and get cards based on your reactions and equations.

Spaced repetition

Cards you miss come back sooner, and cards you know move further out, so you spend less time on what you already remember.

Export when you need it

Plus and Pro users can export to Anki, CSV, PDF or DOCX, so your reaction cards work in the tools you already use.

How it works

Upload your source

Add the chapter PDF, lecture slides, or a photo of your notes on reaction types and balancing.

Review the cards

Check the generated fronts and backs, and edit any card that does not match how your teacher defined the reaction.

Study on a schedule

Work through the deck in the browser, and let spaced repetition bring back the reactions you are most likely to forget.

Start with the reaction types on your next test, such as synthesis, decomposition, single replacement, double replacement and combustion, then add cards for balancing, energy changes and conservation of mass as the unit moves on.

Frequently asked questions

How many flashcards should I make for chemical reactions?

Most students work with 20 to 40 cards per unit, covering each reaction type, its signs, and a balancing example. Start with the reactions on your next test and add more as the course moves on.

How do I study balancing chemical equations with flashcards?

Put the unbalanced reactants and products on the front and the balanced equation with coefficients on the back. Spaced repetition brings the harder equations back before you are likely to forget how to balance them.

Can I export chemical reactions flashcards to Anki?

Yes, export to Anki is included in Plus and Pro, and Plus also adds CSV, PDF and DOCX export. The Free plan lets you study flashcards in the browser with 3 generations per month.

Do I need a credit card to try it?

No, you can start on the Free plan without a credit card. Students also get 40% off paid plans with a school email.
