Question

the correct formula of rust is​

Answer 1

Answer:

Fe2 O3 is the chemical formula for rust

Answer 2

Answer:

$Fe_{2}O_{3}$ is the common formula of rust

Explanation:

Rust is a rough, browny layer formed over an iron material. It is formed due to the reaction of iron to the atmospheric oxygen and water. When they react together, they form this $Fe_{2}O_{3}$.

$2Fe + H_{2} O+O_{2} --->Fe_{2}O_{3}+H_{2}$ is the chemical equation of rust formation
