Answer:
Susana's red crystal sample is a compound because it was broken down into a gas and blue powder. It is not an element because elements cannot be broken down into simpler substances by ordinary means, such as heating.
Explanation:
The red crystals heated by Susana are a compound because they released a gas and turned into a blue powder when heated, indicating a chemical change.
The sample of red crystals that Susana heated up is a compound, not an element. We can come to this conclusion because when the sample was heated, a gas was released and a different substance, a blue powder, was left behind.
This indicates a chemical change had occurred, where the original substance decomposed into different substances. Compounds are known to break down into simpler substances or elements under certain conditions.
An example similar to this would be when blue copper sulfate loses water and becomes white upon heating, or when mercury(II) oxide is heated and decomposes into mercury and oxygen.
