Corrosion

we call them hydrides. Hydrides are forming by the reaction.
This is the definition of a compound: a substance that contains atoms of two or more chemical elements held together by chemical bonds.
They aren't. Double displacement (metathesis) sometimes forms a precipitate, but not always, and it would be silly to call it a "precipitation reaction" if no precipitate was formed. Formation of a precipitate is, however, one way to tell that a reaction has occurred. If everything just stays in solution, then it's meaningless to call it a "reaction" since there has been no change. The evolution of a gas is another method for determining that a reaction has occurred, as is a change in color (this often indicates a change in oxidation state as well, though not always).
The results of a chemical reaction are called the products, and the reactants are what goes into the reaction
Corrosion is the oxidation of metals in general. Rusting is the oxidation of iron in particular.
oxidation
ok im not shore but i think its called reduction

A reaction where oxygen is removed is called reduction. Reduction involves gaining electrons or decreasing the oxidation state of an element or molecule.
When Oxygen is added to a substance it is called oxidation.

They react with a oxydation reaction , forming oxydes. For example: Iron (Fe) reacts with the equation, 2 Fe(s) + O2(g) + 2 H2O(l) = 2 Fe(OH)2(s) Fe(OH)2 is rust. or with the formation of hydroxides: 2 Na + 2 H2O = 2 NaOH + H2
