Chemical Substances: Chem-Quiz 3.4.0

Are you familiar with the formulas of Ammonia or Hydrogen Peroxide? Or perhaps you've been wondering about the structure of Benzene?

With our app, you can learn about over 300 chemical substances commonly studied in introductory and advanced chemistry classes.

The app covers four main levels of study:

1. Inorganic Chemistry: This level explores compounds of metals (such as lithium hydride LiH) and non-metals (carbon dioxide CO2). It also covers inorganic acids (e.g., sulfuric acid H2SO4), salts (including common salt - sodium chloride NaCl), and polyatomic ions.
2. Organic Chemistry: At this level, you'll delve into hydrocarbons (ranging from methane to naphthalene) and carboxylic acids (from formic to benzoic acid). Additionally, you'll learn about natural products, including 20 common amino acids and nucleic bases that make up RNA and DNA molecules. This level also covers important functional groups and classes of organic compounds.
3. Periodic Table: Study all 118 chemical elements, divided into Periods 1-7.
4. Mixed Compounds: This level encompasses various topics, such as systematic and trivial names, structures and formulas, organic, inorganic, and organometallic compounds, acids and oxides, hydrocarbons, alcohols, as well as two levels of difficulty with 100 easy and 100 difficult chemicals.

You can choose from three different game modes:

1. Spelling Quizzes: Test your knowledge by guessing the word letter by letter. There are both easy and hard levels available.
2. Multiple-choice Questions: Challenge yourself with multiple-choice questions that come with 4 or 6 answer options. Keep in mind, you only have 3 lives.
3. Time Game: See how many answers you can provide in just 1 minute. To earn a star, you'll need to give more than 25 correct answers.

In addition, the app offers two valuable learning tools:

• Flashcards: Browse through all the compounds and their formulas without the need to guess.
• Table of Substances: Access a comprehensive table of all substances in the app.

The app is available in multiple languages, including English, German, Spanish, and more. This means you can even learn the names of chemical compounds in foreign languages.

For those who wish to remove advertisements, an in-app purchase option is available.

This app is an excellent resource for any student preparing for chemistry quizzes, exams, and chemistry olympiads.
