Is hydrogen burns in chlorine gas chemical or physical change?
When you combust hydrogen in air, the hydrogen will combine with oxygen to form water. Therefore, the hydrogen and oxygen are undergoing a chemical change to become bonded together producing H2O: 2H2 + O2 → 2H2O + Heat

Do isotopes with the same elements have the same physical properties?
The physical properties are of course different. The chemical properties are considered identical but this is not a general rule; for example hydrogen isotopes (1H and 2H) have some different chemical and biochemical properties.
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
What are the chemical properties of hydrogen peroxide?
