Decomposition is a chemical change because the nature of the compound that has decomposed is now a different or several different chemicals after decomposition. It cannot be converted back to what it was, and so this is a chemical change.

Is decomposition a physical or chemical property?

Decomposition is the process of a compound breaking up into the elements it was comprised of. For example, in electrolysis water decomposes to create hydrogen and oxygen. Because the chemical bonds holding the hydrogen and oxygen molecules were broken, decomposition is a chemical change.


Is it a chemical change when a compound splits into its original elements?

Yes, that would be a decomposition reaction.


What kind of change occurs when a compound separates?

When a compound separates, it undergoes a physical change, not a chemical change. This means the chemical composition of the compound remains the same even though its physical state may have changed (e.g. from solid to liquid).


What type of change is needed top break down a compound?

A chemical change is needed to break down a compound into simpler substances. This typically involves breaking the chemical bonds holding the atoms together in the compound through reactions like decomposition or hydrolysis.


Is decomposition a type of chemical reaction?

Yes, decomposition is a type of chemical reaction. This chemical reaction breaks down a compound into its individual elements.


Is heating ammonium bicarbonate a physical or chemical change?

Heating is a physical process but thermal decomposition is a chemical process.


Can ammonia be broken down by chemical change?

The formula for the decomposition for ammonia would be 2NH3 --> N2 + 3H2


What is another chemical change?

Thermal decomposition is a chemical change.


Is decomposition a type of reaction?

Is decomposing a chemical or physical change?

Decomposition of any compound e.g. when heated CaCO3 compound decomposes to CaO and CO2 compounds, gives different substances and hence a chemical change. Y.Ozkalay

This kind of reaction is called "decomposition".


How does thermal energy cause substances to undergo chemical change how does thermal energy cause substances to undergo chemical change?

Thermal energy cause thermal decomposition of a compound; the bonds between atoms are weakened.
