Question

Consider the equation 4 Fe+3o2 -2Fe2o3 in this equation, 3 o2 is a ?

Answer 1

Explanation :

Corrosion is the process of conversion of metal into its oxides, hydroxides and sulfides.

Rusting of iron is the process of corrosion in metals. Iron objects react with oxygen in the air and turned reddish. This reddish covering is Rust.

`4Fe+3O_2\rightarrow 2Fe_2O_3`

where,
`Fe` is iron

`3O_2` is oxygen present in atmosphere

and
`2Fe_2O_3` is rust or Ferric oxide.

In the given equation,
`4Fe` and
`3O_2` both are reactants and
`2Fe_2O_3` is a product.
