Adouble replacement reaction occurs when hydrosulfuric acid (h2s) is mixed with an aqueous solution of iron (iii) bromide. what is the correct balanced chemical equation for this reaction?
3h2s(aq) + 2febr3 (aq) 2feh3(aq) + 3sbr2(s)
hs(aq) + febr(aq) hbr(aq) + fes(s)
h2s(aq) + febr3(aq) hbr(aq) + fe2s3(s)
3h2s(aq) + 2febr3 (aq) 6hbr(aq) + fe2s3(s)
