What do chemists do? Please choose the best answer
- A.
  
  They mix chemicals
- B.
  
  They study matter and how it changes
- C.
  
  They create new drugs
- D.
  
  They analyze substances
Correct Answer
B. They study matter and how it changes

Explanation
Since chemistry is the study of matter and how it changes, chemists do exactly that.
Some of the other answers are true but are examples of what a chemists may do, not what he or she does overall.

What is a chemical?
- A.
  
  A pure form of matter, also known as a substance.
- B.
  
  A dangerous form of matter
- C.
  
  A toxic form of matter
- D.
  
  A chemical is a mixture of elements
Correct Answer
A. A pure form of matter, also known as a substance.

Explanation
Chemists use a very broad definition of a chemical: it is a pure form of matter,also known as a substance. It does not have to be toxic or dangerous, although in common usage it may have that connotation. It can be a single element such as gold, or a combination of elements such an methane. However those atoms must be bonded together to form a single substance: a chemical is a pure form of matter, not a mixture.

Scientist use chemistry to provide ____________ answers to problems, which arguably provide the deepest answers to many problems.
- A.
  
  Mathematical
- B.
  
  Molecular
- C.
  
  Subatomic
- D.
  
  Long
Correct Answer
B. Molecular

Explanation
A molecular answer to a problem is often full of useful information, since from that structure one can determine physcial and chemical answers, and with that foundation, biological or even psychological answers, for example, follow. A chemical structure is often the root answer to any matter-based topic.

What is a substance?
- A.
  
  A single chemical or a mixture of chemicals
- B.
  
  Two or more atoms bonded together
- C.
  
  Any small sample which has been chemically investigated
- D.
  
  A pure form of matter
Correct Answer
D. A pure form of matter

Explanation
A substance is a pure form of matter.
It many be a single element or atom (in which case there are no bonds), it cannot be a mixture.

The study of how matter changes is the __________study of matter
- A.
  
  Physical
- B.
  
  Chemical
- C.
  
  Biological
- D.
  
  Toxicological
Correct Answer
B. Chemical

Explanation
Scientists define chemistry as the study of matter and how it changes to emphasive both the physical study of matter (not changing it's structure) as well as the chemical study of matter - converting it into other substances.
By changing matter we are not converting it into other elements or energy, we are simply rearranging the atoms we start with- this is chemical change. Converting one element such as hydrogen into another element such as helium (which liberates huge amounts of energy) is a nuclear process, not a chemical process.
