About Chemistry Quiz
Baking soda fizzing in vinegar, rust on a bike chain and bubbles in a soft drink are all chemistry. The Chemistry Quiz starts with everyday changes like these and builds up to atoms and molecules, formulas, acids and bases, the states of matter and how reactions work, with a few famous chemists, such as Marie Curie and Ernest Rutherford, along the way. Questions use plain language and metric units, and each explanation shows the idea behind the answer. It is a good partner to the Periodic Table Quiz when you want to learn what the elements actually do.
How to play Chemistry Quiz
- Press Start for the first of ten questions. The clock starts with it and stops at your last answer.
- Each question asks about atoms, formulas, acids and bases, states of matter or famous chemists.
- Tap an answer, or press 1 to 4 (or A to D) on a keyboard. Answers are final: you see the right one and a one-line explanation, then press Next.
- Most correct answers ranks first, then the fastest time. Only a member’s first finished quiz of the day counts for the leaderboard.
Tips & strategy
- Learn the names of state changes as pairs: melting and freezing, evaporation and condensation, sublimation and deposition.
- pH runs from 0 to 14: below 7 is acid, above 7 is base, and pure water sits at 7.
- Many formulas are short and worth knowing by heart: water, carbon dioxide, table salt and oxygen gas turn up again and again.
