Fundamentals L Exercises

[Will Skinner]

In the textbook, on the Fundamental problem L.35, we are given the following chemical reactions:

Fe +Br2 → FeBr2

FeBr2 + Br2 → Fe3Br8

FeBr2 +Na2CO3 → NaBr + CO2 +Fe3O4

I was unable to balance the last one and I realized that the product of the second was not the reactant of the third. Am I correct in assuming this is a typo? Is the reaction supposed to be Fe3Br8 +Na2CO3 → NaBr + CO2 +Fe3O4 ?

[Sonel Raj 3I]

Yes, it is a typo! Lavelle has the known errors for the solution manuals on his website, FeBr2 is supposed to be Fe3Br8 in the third reaction, you are correct :)

[Mohamed Mido]

Yes it is a typo. It should be Fe3Br8. I looked at the solution manual and it had it as Fe3Br8 not FeBr2.
