Is formation of water when hydrogen burns a chemical change or a chemical property?
It's a chemical change. Any time you have a change in the chemical formula of a substance, you have a chemical change. The chemical formula of hydrogen is H[2], and the chemical formula of oxygen is O[2]. The chemical formula of water is H[2]O. 2 H[2] + O[2] --> 2 H[2]O. If you were watching this happen in a lab, you'd watch two colorless gases react to form a single colorless liquid. A change in state (solid, liquid, or gas) that cannot be due to heating or cooling is nearly always a sign of a chemical change.
