The chemicals have to be in contact with each other in order for any type of chemical reaction to take place. One of the most common examples of a chemical reaction is the rusting of a fence. The combining of the metal and the oxygen causes bonds to break and new ones to be created, which results in the creation of iron oxide or rust.
The ear canal cleans itself with a waxy secretion called cerumen. Cerumen is resistant to water, sticky (to trap dust) and migrates out of the ear canal to self-clean the ear. Sometimes, the wax builds up and causes symptoms, including mild deafness and a sensation of fullness inside the ear.
Ear wax is important to protect the inner ear from bacteria, fungi and â¦ insects, and also aids in lubrication and cleaning. = Earwax = Cerumen, more commonly know as earwax, is produced by glands in the ear canal. It protects deeper areas of the ear by catching dust and other particles.
