How can a chemical change help tell the difference between a element and a compound?

Answer 1

its simple, seeing as how you are breaking a compound down which consists of 2 pure substances. Means that there is a chemical change via taking one pure substance out which will inturn change it chemically and physically

Answer 2

A chemical change is where the chemical properties are changed, when somthing decomposes it is converted into a simpler compund or its elements.

For example the decomposition of Hydrogen peroxide

2H2O2 --> H2O + O2

Hydrogenperoxide is a toxic chemical, where as we depend on water and oxygen to survive.

So clearly the chemical properties have changed.

Answer 3

Answer 4

Chemical changes are needed to break down a compound because there is a change in the physical structure of the compound. Certain chemicals are substituted for each other, taken away, or even added to the compound in these reactions.

Answer 5

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.

Answer 6

no, an element cannot be broken down into anything simpler by a chemical or physical change.
