The chemical formula for iron(II) chromate is FeCrO₄. Here's how we get there:

* Iron(II): This indicates that iron has a +2 charge (Fe²⁺).

* Chromate: This is the polyatomic ion CrO₄²⁻.

* Balancing Charges: To balance the charges, we need one Fe²⁺ ion and one CrO₄²⁻ ion.

Therefore, the formula is FeCrO₄.
