Answer:
Physical properties are involved when ice melts to form water and that water boils to form steam
Explanation:
This is because there in no chemical reaction taking place, just a physical change.
A physical change in a change in which the chemical structure of the substance does not change. Ice, water and steam are all the same on a molecular level, thus changing from ice to water or from water to steam are physical changes.
Answer:
(a).
![order \: of \: A = 2 \\ order \: of \:B = 0 \\ rate = k[A] {}^{2} [B]](https://tex.z-dn.net/?f=order%20%5C%3A%20of%20%5C%3A%20A%20%3D%202%20%5C%5C%20order%20%5C%3A%20of%20%5C%3AB%20%20%3D%200%20%5C%5C%20rate%20%3D%20k%5BA%5D%20%7B%7D%5E%7B2%7D%20%5BB%5D)
(b)
(c). The rate increases because kinetic energy of reactant molecules increases.
A chemical property refers to that which cannot be physically determined. From the choices given above, the chemical property of one of the student's materials is the reactivity of the copper strip. Thus, the answer to this item is letter B.
