Question

Josh used several different liquid chemicals for an experiment in his chemistry class. After completing the experiment, the chemicals were no longer usable. Josh carefully poured each chemical into a bottle marked "Waste" and placed the lid back on the bottle. Did Josh use the correct procedure?
A.
No; different types of chemical waste should not be mixed together.
B.
No; the chemicals should have been poured down the sink.
C.
No; the chemicals should have been poured into the trash can.
D.
Yes; the chemicals were stored in the proper place.

Answer 1

The answer is A (No; different types of chemical waste should not be mixed together).

This should be complete common sense, but the answer B is incorrect because chemical SHOULD NOT be poured down a drain because It can go out into the sewer. C is wrong because it can go through the trash can or into the dump and contaminate other things.
