change in energy
color change
evolution of a gas

Explanation:

When two clear solutions are mixed and turn yellow, this is a color - change indicator of a chemical reaction. The formation of a yellow solid that sinks to the bottom is the formation of a precipitate, another indicator of a chemical reaction. There is no mention of a change in energy or evolution of a gas.
