Asked by .jimin
This flask originally held some copper wire and a clear solution of nitric acid. The two substances reacted and produced a brown gas and a blue solution. This reaction cannot be reversed. Evidence of a chemical reaction is shown by...
A) ice forming.
B) steam rising.
C) the formation of a gas.
D) a change in state from a solid to a liquid.
Is it "C?" I'm guessing that is the correct answer. If anybody can, please explain it to me so I won't have to ask again. Thank you.
