Wool is primarily made up of a protein called keratin, which gives it its unique chemical properties. It is hydrophobic, meaning it repels water, and has a high moisture content which helps regulate temperature. Wool is also flame-resistant and has good elasticity, allowing it to maintain its shape even after stretching.
If it's a chemical, it has chemical properties. An oreo churro (whatever unholy abomination that might be) is a mixture of chemicals, each of which will have their own chemical properties.
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.
A chemical reaction changes the chemical properties of substances involved by forming new substances with different chemical compositions. This can result in changes in physical properties such as color, temperature, odor, and state of matter.
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.
No; each chemical element has different properties.
