Question

A double 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) yields 2FeH3(aq) + 3SBr2(s)
HS(aq) + FeBr(aq) yields HBr(aq) + FeS(s)
H2S(aq) + FeBr3(aq)yields HBr(aq) + Fe2S3(s)
3H2S(aq) + 2FeBr3 (aq) yields 6HBr(aq) + Fe2S3(s)

Answer 3

3 H2S(aq) + 2 FeBr3(aq) = Fe2S3(s) + 6 HBr(aq)

Answer 4

option D

Answer 5

wait how did you get that?

Answer 6

write down the chemical equation first.......we know that its a double displacement reaction where hydrogen will attach to bromine and iron with sulfate

Answer 7

it goes like this H2S + FeBr3 = HBr + Fe2S3

Answer 8

from here it's just a matter of figuring out the coefficient, Which looks something like H2S(aq) + 2FeBr3 (aq) yields 6HBr(aq) + Fe2S3(s)

Answer 9

yay thank you so very much!!
