What is matter?
- A.
Anything that has mass
- B.
Anything that has mass or takes up space
- C.
Anything that has mass and volume
- D.
As the word implies, matter is anything that is important
Correct Answer
C. Anything that has mass and volumeExplanation
matter is defined as anything that has mass and takes up space. Note the only reason to include the volume (taking up space) requirement is for oddball situations that may be hypothetical only such as a black hole (all mass and no volume) or a perfect vacuume (volume but no mass). Most chemists might think that all matter is important but that's just an opinion.Rate this question:

Which of the following is an example of matter?
- A.
Happiness
- B.
Energy
- C.
A proton
- D.
Velocity
Correct Answer
C. A protonExplanation
A proton has mass and takes up space so it is an example of matter; albeit a small amount. The others are not matter-based and therefore are not examples of matterRate this question:

What do all chemists do?
- A.
They all smoke cigarettes
- B.
They study the elements of life
- C.
They mix chemicals
- D.
They study matter
Correct Answer
D. They study matterExplanation
Since chemistry is the study of matter and how it changes, all chemists study matter. They may only study gold for example, which is not an element of life. They may be physical chemists, meaning they have no need to mix chemicals. Hopefully very few of them smoke cigarettesRate this question:

- 5.
A chemist walks into his laboratory, and mixes some chemicals, then using a device known as a NMR (nuclear magnetic resonance) spectrometer determines the structure of his new substance, which he finds is a useful medicine. In chronological order, what three types of chemist has he behaved as?
- A.
Organic, analytical, medicinal
- B.
Synthetic, polymer medicinal
- C.
Combinatorial, analytical, synthetic
- D.
Synthetic analytical, medicinal
Correct Answer
D. Synthetic analytical, medicinalExplanation
He is a synthetic chemist while mixing chemicals, analytical while analyzing them by NMR and medicinal while determining that he has made a useful drugRate this question:
