Physical: abrasion, crystallization, insolation, melting and freezing.
Chemical: hydration, oxidation(rust), carbonic acid action, and hydrolysis
Answer: C.
Explanation:
The rusting of Clara's bike in which iron changes to rust is a chemical change. In a chemical change: the process is not easily reversible.
55.80 C/12= 4.65/2.3225= 2
7.04 H/1= 7.04/2.3225= 3
37.16 O/16= 2.3225/2.3225= 1
Empirical Formula= C2H3O
301.35/43= 7
(C2H3O)7= C14H21O7= Molecular Formula
I would say if you would add colors it would be the best
