Question

question 2 of 10
why is chemistry a science, but alchemy was not?
a. chemistry uses experiments to test ideas, whereas alchemy used evidence.
b. chemistry is done by chemists, whereas alchemy was done by aristotle.
c. chemistry deals with many elements, whereas alchemy dealt with only four elements.
d. chemistry uses experiments to test ideas, whereas alchemy used superstitious practices.

Explanation:

Chemistry is a scientific discipline that relies on experimental methods to test hypotheses and validate theories. Alchemy, on the other hand, was more of a mystical and superstitious practice that often involved beliefs in transmuting base metals into gold and finding the elixir of life without a solid scientific foundation. Option A is incorrect because alchemy did not use evidence in a scientific sense. Option B is wrong as alchemy was not solely done by Aristotle. Option C is inaccurate as the number of elements dealt with is not the key differentiating factor. Option D correctly highlights that chemistry uses experiments (a scientific approach) while alchemy used superstitious practices.

Answer:

D. Chemistry uses experiments to test ideas, whereas alchemy used superstitious practices.
