B. Because when two different chemical properties combine that makes a chemical reaction .. Example) Sugar and tea combined makes sweet tea or a necklace is sitting in water for weeks and turns the metal to rust ... Thier both different once.combined it makes a chemical reaction ....

 c.)The product only has different physical properties than the reactants because a chemical reaction occurred. This is because rust can behave differently than oxygen and iron. This is because a chemical reaction has happened- a chemical reaction is when a new product is formed. Rust can be change chemically and physically.
