Many metals are chemically active elements and get easily affected by substances like moisture, air, acids, etc. One must have observed iron articles that are shiny when new, but get coated with a reddish brown powder when left for some time. This process is commonly known as rusting of iron. The problem with iron (as well as many other metals) is that oxidation takes place and the oxide formed does not firmly adhere to the surface of the metal causing it to flake off easily. This eventually causes structural weakness and disintegration of the metal.
When a metal is attacked by substances around it, it is said to corrode and this process is called corrosion. Corrosion causes deterioration of essential properties in a material.
What happens to copper vessels or artifacts when exposed to air and water? They slowly get tarnished by acquiring a thin green oxide layer. Similarly, silver quickly acquires a thin black oxide coating in moist air. The heaviest metal lead also tarnishes in moist weather. The black coating on silver and the green coating on copper are examples of corrosion in which the oxides formed strongly bond to the surface of the metal, preventing the surface from further exposure to oxygen and consequently slowing down corrosion.
Fuels burning is an oxidation reaction.
corrosion of metal substances
Redox reactions are VERY important, and have formed the basis of much of what we have discovered, if not directly than indirectly. You will most likely agree with me in saying that the invention of a battery, be it an immobile cell or a portable power source, is an important event in history, correct? Well, the first batteries produced, such as the Voltaic Pile and the Daniell Cell, are actually examples of a redox reaction, where electrons move from chemical to another, changing the chemical species of each as it occurs. For example, in the Daniell cell, copper in a copper nitrate solution and zinc in a zinc nitrate solution have different reduction or oxidation potentials, and thus can induce an electron flow in both an internal circuit (such as a salt bridge- paper soaked in an ionic solution, an electrolytic solution) and an external circuit (such as your device that is powered by the battery).
The products of oxidation of organic compounds vary widely. There are tens of millions of organic compounds. And are they going to be completely oxidized, or is partial oxidation a maybe? Waaaaaaay too many possibilities to even begin to explore them here.
To prevent harmful microbes, practice good hygiene by washing your hands regularly with soap and water, properly cooking and storing food, keeping your living spaces clean, and avoiding close contact with sick individuals. Additionally, vaccination, staying up to date on immunizations, and practicing safe food handling techniques can also help prevent the spread of harmful microbes.
Oxidation: rancidity , corrosion ,Oxidation reactions occur in the batteries, we use daily. Oxidation of Fruit and Vegetable Slices ,Decay of living matter by atmospheric oxidation, into CO2 and H2O reduction (i'm not so sure! but still): FUELING THE SPACE SHUTTLE. , COMBUSTION AND EXPLOSIONS , EXPLOSIVES , The primary process of reducing ore to produce metals is discussed in the article on Smelting.
By taking the oxygen for itself in order to prevent oxidation from taking place. For this reason, antioxidents need to be replenished daily.

No it's not harmful in healthy males.
Three different types of chemical reactions seen in everyday life include combustion reactions (burning a candle), oxidation-reduction reactions (rust forming on metal), and acid-base reactions (antacid tablets neutralizing stomach acid). These reactions help drive processes like cooking, cleaning, and metabolism.

In reasonable doses - a daily amount of max. 5 g - NaCl is not harmful.
Salt can be harmful for the heart if the daily intake is greater than 2,5-5 g.
2 Mg + O2 gives 2MgO
it releases harmful radio active waves which s harmful to all living organism
yes
