Dissolved Oxygen(usually between 20 - 60 ppm) reacts with H2O and the delocalized (conductive) electrons on the surface metal O2 + H2O + 4e- to form 4(OH)- ions that in turn draw the now charged (Fe2+) ions out into solution as 2Fe(OH)2...RUST
catylst for rusting due t high reactive form.
The mechanism is poorly understood because it takes place on the surface of an insoluble particle, a difficult situation to probe experimentally. The mechanism shown below is one of several models proposed to at least partially explain the action of the Ziegler-Natta systems, but it is only an approximation of the more complex process that actually occurs.

Generally polar solutes are dissolved in polar solvents and nonpolar solutes are dissolved in nonpolar solvents.

While two people proposed continental drift (Alfred Wegener and Alexander du Toit), it was just ONE scientist Harry Hess that proposed the mechanism of sea floor spreading to explain how the continents actually moved.

Dry corrosion occurs when the metal reacts with oxygen in the air.
Explain the access mechanism of a Magnetic disk. How is this access mechanism different in RAID level 5?

Darwin lacked a sensible mechanism of heredity. His concept of blending was so off the mark that a Scottish engineer showed that evolution could not take place with the mechanism Darwin proposed. Mendel's concept of particulate inheritance was the correct solution to this problem.

in order to explain the mechanism of enzymes action a German chemist Emil fischer,in 184,proposed the lock and key model.According to this model both the enzymes and the substrate possess specific complementary geometric shapes that fit exactly into one another.This model explain enzyme specificity.

To explain the species problem, " that mystery of mysteries " which was the natural history problem of the day. From his observations and experiments Darwin proposed his theory of evolution by natural selection, which provided a mechanism for the observed fact of evolution.
