yes- you cannot convert it back into its original form
Burning is a VERY useful chemical reaction. Automobile engines depend of burning- as does the furnace that heats your home, and the oven that bakes your bread, or the power plant that burns oil, coal or natural gas to make electricity.
Burnig things is always a chemical change.

Chemical reaction
Combustion is a chemical reaction.
No. A chemical reaction is not alive.
A new chemical substance is formed during a chemical reaction by rearranging the atoms of the reactants. The products of a chemical reaction have different properties compared to the original reactants.
A chemical reaction is a graphical representation of a chemical reaction.
A chemical reaction is represented by a chemical equation.
A chemical reaction can be represented by a chemical equation.
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
The reaction must change the chemical nature of reactants.
