Yes. Ethane can undergo combustion, in which it reacts with oxygen to produce carbon dioxide and water.
2C2H6 + 7O2 --> 4CO2 + 6H2O
Yes. Ethane can undergo combustion, in which it reacts with oxygen to produce carbon dioxide and water. 2C2H6 + 7O2 --> 4CO2 + 6H2O
Yes
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. Ethane can undergo combustion, in which it reacts with oxygen to produce carbon dioxide and water. 2C2H6 + 7O2 --> 4CO2 + 6H2O
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.
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.
of course, by the intermediate of chemical reactions
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 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.
