Here is the step-by-step breakdown to solve this worksheet:
1.
Question 1: "This branch of Chemistry studies the properties and changes of matter and their relationship to energy."
*
Reasoning: This is the classic definition of Physical Chemistry. It deals with the physical properties of molecules (like heat, light, electricity) and how they change.
*
Answer: d. physical
2.
Question 2: "This branch of Chemistry studies non-carbon-containing compounds."
*
Reasoning: Organic chemistry focuses on carbon. Inorganic chemistry focuses on everything else (metals, minerals, salts). Therefore, "non-carbon" points to Inorganic.
*
Answer: b. inorganic
3.
Question 3: "This branch of Chemistry identifies the composition of materials."
*
Reasoning: Analytical chemistry is all about figuring out what something is made of (qualitative analysis) and how much of it is there (quantitative analysis).
*
Answer: a. analytical
4.
Question 4: "This branch of Chemistry studies the substances and processes in living things."
*
Reasoning: The key phrase here is "living things." Biochemistry is the study of chemical processes within and relating to living organisms.
*
Answer: c. biochemistry
5.
Question 5: "This branch of Chemistry studies non-carbon model uses."
*
Reasoning: This phrasing is slightly awkward, but it mirrors Question 2. If we are looking at non-carbon based models or substances, we are back in the realm of Inorganic Chemistry.
*
Answer: b. inorganic
6.
Question 6: "This branch of Chemistry uses mathematics and computers to design and predict substances."
*
Reasoning: Theoretical chemistry uses math and computer simulations to understand and predict chemical behavior.
*
Answer: f. theoretical
Final Answer:
1. d. physical
2. b. inorganic
3. a. analytical
4. c. biochemistry
5. b. inorganic
6. f. theoretical
