Question

6. What is the formula of Rust?
[ ]
a. Fe2O3
b. Fe3O4
c. Feo
d. None of these​

Answer 1

$\huge{\underline{\mathtt{\blue{A}\red{N}\pink{S}\green{W}\purple{E}\orange{R}}}}$ Fe2O3

Providing the electrons for the above reaction is the oxidation of iron that may be described as follows: Fe → Fe2+ + 2 e. The following redox reaction also occurs in the presence of water and is crucial to the formation of rust: 4 Fe2+ + O2 → 4 Fe3+ + 2 O.

It's formula is Option A

Fe2O3

Answer 2

Answer:

Fe203

Explanation:

Providing the electrons for the above reaction is the oxidation of iron that may be described as follows: Fe → Fe2+ + 2 e. The following redox reaction also occurs in the presence of water and is crucial to the formation of rust: 4 Fe2+ + O2 → 4 Fe3+ + 2 O.

Rust is the common name for a very common compound, iron oxide. Iron oxide, the chemical Fe2O3, is common because iron combines very readily with oxygen -- so readily, in fact, that pure iron is only rarely found in nature.
