Do you Know the Formula of Ammonia? Or Hydrogen Peroxide? What is the Structure of Benzene? Learn more than 300 chemical substances that are studied in introductory and advanced chemistry classes.
There are four large levels:
1. Inorganic Chemistry: compounds of metals (such as lithium hydride LiH) and non-metals (carbon dioxide CO2); inorganic acids (for example, sulfuric acid H2SO4), salts (including common salt - sodium chloride NaCl), and polyatomic ions.
2. Organic Chemistry: Hydrocarbons (from methane to naphthalene) and carboxylic acids (from formic to benzoic acid). Natural products, including 20 common amino acids and nucleic bases that are part of RNA and DNA molecules. You can also study the most important functional groups and classes of organic compounds.
3. All 118 chemical elements and the periodic table: the questions are divided into Periods 1–7.
4. Mixed compounds:
* systematic and trivial names;
* structures and formulas;
* organic, inorganic, and organometallic compounds;
* from acids and oxides to hydrocarbons and alcohols;
* two levels: 100 easy and 100 difficult chemicals.

Choose the game mode:
1) Spelling quizzes (easy and hard) - guess the word letter by letter.
2) Multiple-choice questions (with 4 or 6 answer options). It’s important to remember that you have only 3 lives.
3) Time game (give as many answers as you can in 1 minute) - you should give more than 25 correct answers to get a star.
Two learning tools:
* Flashcards where you can browse all compounds and their formulas without guessing.
* Table of all substances in the app.

The app is translated into 12 languages, including English, German, Spanish, and many others. So you can learn the names of the chemical compounds in foreign languages.
Advertisements can be removed by an in-app purchase.

It is a perfect app for every student preparing for chemistry quizzes, exams, and chemistry olympiads.
