Rust
Here :
Fe2O3 + xH2O-> Fe2O3.xH2O(Rust)
FeO + xH2O-> No visible change
x is any number of water molecules.
If you express your answer as a chemical equation with all forms given, you would get: Mg+(g) + e- -> Mg (g)
The chemical equation is:3 NaOH + FeBr3 = 3 NaBr + Fe(OH)3
This is not a chemical formula or equation.
