A science lab, Cash mixes two clear liquids together in a beaker. Bubbles are produced, and a white solid forms and settles to the bottom. He plans to heat the beaker over low heat and make more observations.
Which statement is most likely correct?
A physical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
A physical change occurred, so even if Cash heats it, the white solid will remain.
A chemical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
A chemical change occurred, so even if Cash heats it, the white solid will remain. four
