Question

The chemical formula of Rust is _____

Answer 1

• The hydrated Ferric oxides are called Rust.
• These oxides are abundant in nature as Iron $\left(Fe\right)$ mixes with Oxygen $\left(O_2\right)$
• This rusting is an oxidation reaction.

Hence, the chemical formula of Rust is $\left(F{e}_2{O}_3.x{H}_{2}O\right)$
