Question

In 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?
1.A physical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
2.A physical change occurred, so even if Cash heats it, the white solid will remain.
3.A chemical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
4.A chemical change occurred, so even if Cash heats it, the white solid will remain.
