chemical formula for Fe + ZnSO4

To determine the chemical formula for the reaction between iron (Fe) and zinc sulfate (ZnSO4), we need to consider the charges of the individual elements.

Iron (Fe) is a transition metal and can form different ions with various charges. The most common forms are Fe2+ (iron(II) ion) and Fe3+ (iron(III) ion).

Zinc sulfate (ZnSO4) consists of zinc (Zn) and sulfate (SO4) ions. The sulfate ion has a charge of 2- (SO4^2-).

To balance the charges between the elements, we need to use the crisscross method. In this method, we cross the absolute values of the charges and place them as subscripts for the opposite element.

Since the sulfate ion has a charge of 2-, and zinc (Zn) has a +2 charge (Zn^2+), we do not need to change the subscripts for the zinc ion.

For iron, we need to consider which form of iron is present. With sulfate having a charge of 2-, we can deduce that one iron(II) ion (Fe2+) will balance out the charge. Therefore, we write Fe^2+ as the subscript for iron in the chemical formula.

The chemical formula for the reaction between iron (Fe) and zinc sulfate (ZnSO4) is:
Fe + ZnSO4 = FeSO4 + Zn
