Question

what is the formula of Rust????​

Answer 1

Answer:

formula of rust is FeSO4.xH2O

Answer 2

Explanation:

The chemical equation for the formation of rust is ...

Iron + Water + Oxygen = Rust

i.e....4Fe (s) + 6H20 (l) + 3O2 (g) = 4Fe(OH)3 (s)

Then Fe(OH)3 dehydrates to produce Fe2O3.nH20 (s)

Thereby, the chemical formula for rust is Fe2O3.nH2O
