Question

michael mixes two chemicals together in a beaker. the chemicals change color, and the beaker heats up quickly. what kind of change most likely occurred? a. a chemical change occurred. b. no change occurred. c. a mixture formed. d. only a physical change occurred.

Explanation:

Chemical changes often involve color - change and heat - release. Mixing two chemicals that result in color change and heat evolution is a sign of a chemical reaction. A physical change would not involve such chemical property alterations, and clearly a change has occurred. A mixture forming is not the most accurate description as it implies no chemical reaction, just combination.

Answer:

A. A chemical change occurred
