Because more than one substance was released (following a color change signifying a chemical reaction), the sample was indeed, a compound.

Sample response: 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.

This is late but if anyone needs it here you go.
