So , I think u chose the right ones

Answer:

I think this three:

  1. A. Sugar is heated until it turns into a brown caramel sauce.
  2. C. Two unknown liquids are mixed together and a gas is produced.

Explanation:

I said (A) because :

  • heating sugar results to caramalization.
  • and in a chemical reaction, a substance forms a new substance with different properties (caramel).

I said (C) because :

  • same because it formed a new substance.

I didn't choose (B) because :
