a. chemistry
b. chemical
Interpretation:
The following terms should be defined:
- Chemistry
- Chemical
Answer to Problem 1.1QAP
Solution:
- Chemistry: The branch of science in which we study the composition, properties and structure of a substance or chemical or matter.
- Chemical: A chemically pure substance which has the same composition and properties irrespective of source, or mode of production.
Explanation of Solution
Chemistry: In this branch of science we study the nature of matter including properties, structure, composition, synthesis. We also study the way chemicals interact with each other and their surroundings. It is a general perception to link chemistry or study of chemicals to laboratory. However chemistry is present everywhere around us. Being photosynthesis, or respiration, or digestion, or food cooking, or corrosion of metals, etc.
Chemical: The chemical is a substance (pure) which will have the same composition irrespective of the source, it means water will always have two hydrogen atoms and one oxygen atom whether we are taking it from the river, sea, rain etc. The chemical formula will remain the same H2O.
We can define chemistry as that branch of science which deals with the study of chemicals, their properties, their structure, synthesis and interaction with other chemicals. Where, chemicals are pure substance which will have a distinct composition (made of same type of and same number of elements) irrespective of the source.

- Dr. X claims that she has found a new remedy (carrot extract) to cure acne. She scores an interview with the science writer for a local newspaper, and gets a brief article written about her and her claims in that newspaper. The article does not contain any experimental evidence, but mentions that Dr. X accidentally splashed some carrot extract on her face and found that the acne was reduced a few days later. Student Y finds the article and cites it as a source for a paper he is writing for class, as evidence that acne has been cured. (a) Is this finding a fact, a theory, a hypothesis, or an observation? Explain why you think so. (b) Was it OK for Student Y to use the newspaper article as evidence for his paper?
