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? 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.

Explanation:

Step1: Understand chemical and physical changes

A chemical change results in the formation of new substances. A physical change does not form new substances. When two clear liquids are mixed and a white solid (new substance) and bubbles (gas, new substance) are produced, a chemical change has occurred.

Step2: Analyze the effect of heating

If a chemical change has occurred, heating the mixture will not reverse it to form the original mixture. The new substances (white solid etc.) will remain.

Answer:

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