Tarnish is a thin layer of corrosion that forms over copper, brass, silver, aluminum, and other similar metals as their outermost layer undergoes a chemical reaction.Oxidation is defined as the interaction between oxygen molecules and all the different substances they may contact, from metal to living tissue. However, Tarnish does not always result from the sole effects of oxygen in the air. For example, silver needs hydrogen sulfide to tarnish; it does not tarnish with only oxygen. It often appears as a dull, gray or black film or coating over metal whereas oxidation usually results in brown or green.

Why are rusting and tarnishing examples of corrosion?
Rusting and tarnishing are examples of slow oxidation, where the naturally occurring oxygen bonds with the metal. Oxidation is a form of corrosion, since oxidation removes solid matter.
Is silverware tarnishing physical or chemical change?
Tarnishing is actually oxidation of the silver, so it would be a chemical change.
Is tarnishing of silverware physical or chemical change?
Yes, specifically it is oxidation.
What is the difference between hydroxylation and oxidation reaction?
There is no difference, these are 2 names for an identical reaction.
List 3 chemical properties?
Three chemical properties are reactivity, flammability, and oxidation state.

What is the difference between b-oxidation and a-oxidation?
State of Hg in Hg2Cl2 is 1
What is difference between valency and oxidation numbre?
There is not much difference in both of them

What is an example for tarnish?
Tarnishing involves oxidation on metal. Some examples include rust on pipes and coins, and corrosion on items made of silver.

Three chemical properties are reactivity, flammability, and oxidation state.
What is rusting Tarnishing and burning?
They are all oxidation. Burning is much faster than the other two and releases large quantities of heat. Rusting and tarnishing are much slower. Tarnishing typically shows a change in color and very little in the way of physical change. Rusting slowly eats away the material as it combines with the oxygen.
What is difference between corrosion resistance and oxidation resistance?
corrosion resistance is resistant against chemicals oxidation resisstance is restant against oxigen
What is the Difference between valency and oxidation state?
Valency is the number of electrons in the valence shell. Oxidation state is the formal charge on an atom/ion.
What is the difference between the two compounds FeBr2 and FeBr3?
The oxidation state of Fe in FeBr2 is +2. The oxidation state of Fe in FeBr3 is +3.
