Substance A is likely an element, as it cannot be broken down by a chemical change. Substance Z is likely a compound, as it can be broken down by a chemical change into simpler substances. From this information, it can be concluded that substances A and Z have different chemical compositions and properties.
An element cannot be broken down into a simpler substance by chemical means.
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
No. Elements cannot be broken down into simpler substances in a chemical reaction.

Substance A is likely an element, as it cannot be broken down by a chemical change. Substance Z is likely a compound, as it can be broken down by a chemical change into simpler substances. From this information, it can be concluded that substances A and Z have different chemical compositions and properties.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
Hexane is a compound. All chemical compounds can be broken down by chemical change (chemical reactions of many types) - not only hexane. All the other choices are elements which cannot be broken down by chemical changes.
