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 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

A chemical change involves the breaking and forming of chemical bonds. Elements consist of one type of atom that do not undergo chemical changes easily, while compounds are made up of two or more different types of atoms which can undergo chemical changes to form new substances. By observing the reaction products of a substance with another, we can determine if it is an element or a compound based on the changes in composition and properties.

Answer 7

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