of course, by the intermediate of chemical reactions
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.
Not necessarily. In some chemical changes a compound is broken down into its elements.
No. It is only a chemical change if the properties of the atom (or in this case ionic compound) are completely changed. This means anytime a chemical bond in that molecule is broken or formed, it's a chemical change.
Substance A is an element, substance Z is a compound.
A compound.A compound is composed of elements. If you were to break down a compound you would get new compounds or elements.
A chemical change can help you tell the difference between an element and a compound because an element is a pure substance that cannot be broken down or separated into other pure substances through chemical change while a substance that is made from two or more elements that have combined in a chemical change are known as compounds.
An acid is a chemical compound, not a physical or chemical change.
Chemical Change
After a chemical change a new compound is formed.
when a chemical change occurs, chemical bonds are broken up
Yes its a chemical change.
Sugar is a (chemical) compound, but not a change at all.
