What components are needed for oxidation to occur?
what must be present for oxidation-reduction to occur?
When materials contain iron are exposed to water and oxygen?
The iron will become oxidized and we will say that it has become rusty.
Number of oxidation iron III?
+3 is the oxidation no of iron(III)
Does a nail rust in oil?
No, in order for iron to rust it must be exposed to oxygen. Since there is no oxygen in oil oxidation cannot occur.
Which two substances must be present for an iron object to rust?
For the oxidation of iron to occur, that is for ferric oxide to form, there must be oxygen present. There must also be water present.
What happens when materials containing iron is exposed with water and oxygen?
oxidation
How long would it take for oxidation to occur on exposed car body metal?
If exposed to the elements, minutes.

Why is tropical red earth red?
The iron in the soil turns red when exposed to oxygen (oxidation). Although iron is common is most soils, oxidation (rusting) is much more pronounced in hot and wet climates.
Why do some fruits change colour when exposed to air?
When fruit flesh is exposed to air, it experiences oxidation, much like iron does. This reaction doesn't result in the rust that iron's reaction does, but it is responsible for the brown coloring that this exposed fruit flesh takes on.
When materials contain iron are exposed to water and oxygen?
The iron will become oxidized and we will say that it has become rusty.
How does water rust a nail?
In the presence of oxygen a reaction occur (oxidation) and the hydrated iron oxide is produced.
What is the oxidation state of iron in Iron chloride?
There are two Iron chlorides. Iron(II) chloride, in which iron is in +2 oxidation state, and Iron(III) chloride, in which iron is in +3 oxidation state.
Occurs when material containing iron are exposed to oxygen and water?
Rusting occurs. The iron is oxidised in this process called oxidation, from Fe [metal] to Fe2+ [ion]. This is evident through the increasing oxidation state of iron from 0 in Fe to +2 in Fe2+. Thus Fe2+ ions will first form FeO [iron (II) oxide] which is a green compound, then since FeO is not a stable compound, it will further be oxidised to form Fe2O3 [iron (III) oxide] which is the reddish-brown compound often referred to as 'rust'.
Number of oxidation iron III?
+3 is the oxidation no of iron(III)
What happens to iron with oxidation?
After oxidation iron is transformed in oxides.
Why is oxidation bad?
oxidation is rust and rust weakens iron, iron is supposed to be strong, and therefore oxidation is bad.
