Question
When drops of one liquid are added to another liquid, a purple powder forms where the liquids meet.
Did the two liquids enter a chemical reaction?

The correct response would be:
**Yes. The mixing of two liquids is a common sign of a chemical reaction.**
When two liquids are mixed and a purple powder (precipitate) forms, this indicates a chemical reaction has likely occurred. The formation of a solid from two liquids is characteristic of a precipitation reaction, which is a type of chemical reaction. The other responses do not accurately describe what is happening in this scenario.
