Final answer:
The chemical property of wood that involves a chemical change is Combustibility where it reacts with oxygen resulting in combustion and transformation into new substances.
Step-by-step explanation:
The chemical property of wood that involves a chemical change is Combustibility. Chemical properties describe a substance's potential to undergo a chemical reaction. Combustibility is a measure of how easily a substance will set on fire, through chemical reactions with oxygen, and lead to combustion.
This is a chemical property because when wood burns, it reacts with oxygen in the air and is transformed into other substances such as carbon dioxide, water vapor, and ash - a process which is indeed a chemical change.
