No it is an element. Elements can't be broken down by chemical action.
Yes
Beryllium is an element, specifically a chemical element with the symbol Be and atomic number 4. It is classified as a metal and is found in the periodic table. As an element, it cannot be broken down into simpler substances by chemical means.
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.

Yes
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.
Beryllium is an element, specifically a chemical element with the symbol Be and atomic number 4. It is classified as a metal and is found in the periodic table. As an element, it cannot be broken down into simpler substances by chemical means.
Yes, ammonia can be broken down by a chemical change. One way to break down ammonia is through a process called decomposition, where it can be broken down into nitrogen and hydrogen gases. This can be achieved through various chemical reactions or by applying heat or using a catalyst.
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.
of course, by the intermediate of chemical reactions
yes they can
Chemical Change
No. It is an element and fundamentally already as "broken down" as possible.
It is a physical change, the chemical form remain unchanged.
