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.

Must a new substance be formed when you observe a chemical propery?
The formation of a new substance is the criterion for a chemical change. You can't have a chemical change without the formation of at least one new substance. As you can't observe a chemical property without setting a chemical change in motion, the answer to your question is yes.

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.
What is a change in which a new substance is formed?
The kind of change that results in the formation of new substances is known as a chemical change or reaction. This will cause alteration of the atoms in the substances.
