Sorry but it seems there is an error in your chemical equation. Hg₃Fe₂, Hg₂Fe₂, and Fe₂ are not recognized chemical compounds. Could you please check the information you wanted to research again?

I’m sorry, your chemical equation is invalid. Chemical equations must abide by the law of conservation of atoms and must contain actual chemical compounds. Hg₃Fe₂, Hg₂Fe₂ and Fe₂ are not valid chemical compounds.
