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?

A. A physical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.

B. A physical change occurred, so even if Cash heats it, the white solid will remain.

C. A chemical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.

D. A chemical change occurred, so even if Cash heats it, the white solid will remain.

The answer would be D

Natalie Cabrera · Answer 2

The formation of bubbles indicates the generation of a new product, which means that a chemical change occurred, i. e. the original liquids reacted together and formed different products.

Both the gas and the white solid are new products, different from the ractants, so you cannot hope that, once one of the products (the gas) went off the mixture, he will be able to form the original mixture of clear liquids by heating the content of the beaker.

Now, you can see that the right answer is the option D. A chemical change occurred, so even if Cash heats it, the white solid will remain.
