Novosadov [1.4K]

Answer:

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

Explanation:

  • 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.

<em>The correct answer would be that a chemical change occurred, so even if Cash heats it, the white solid will remain.</em>

Chemical changes occur when atoms in a substance or mixture of substances are rearranged, leading to the formation of new substances.

<u>In this case, the mixture of the two clear liquids led to the formation of gas in form of bubbles and a white solid forms that settle at the bottom. The formation of these 2 substances from the mixture of the two clear liquid is an indication of chemical reaction/changes. Hence, even if cash heats the resulting mixture, the white solids will likely remain.</u>
