A meaningless question. Because an equation relates the interaction of TWO or more substances, while this question mentions only ONE (namely Iron).


What is the balanced equation of iron plus HCl?

The full equation is: Fe(s) + 2HCl(aq) -> FeCl2(s) + H2(g) The Net Ionic Equation is: Fe2+(s) + Cl1-(aq) -> FeCl2(s) (made necessary corrections, however this is not the net Ionic equation....) Hope that helps!

What is the chemical formula for iron and copper sulfate?

The formula for iron is Fe. The formula for copper sulfate is CuSO4. The chemical equation for the reaction is Fe (s) + CuSO4 (aq) --------- Cu (s) + FeSO4(aq) The iron is a more active metal than copper therefore it replaces the copper in the copper sulfate solution.
