if you mix two clear, colorless liquids together, which of the following observations would indicate a chemical reaction has occurred? a the resulting mixture remains clear and colorless. b the container the liquids are mixed in remains the same temperature. c a solid appears in the tube and settles to the bottom.

Answer

Brief Explanations:

A chemical reaction often leads to the formation of a new substance. Precipitation (formation of a solid from a solution) is a sign of a chemical reaction. Options a and b do not indicate formation of a new substance. Option c shows the formation of a solid (precipitate), which is a strong indication of a chemical reaction.

Answer:

C. A solid appears in the tube and settles to the bottom.
