Re: Question L.35
I think it's supposed to be Fe3Br8 instead of FeBr2 because the result from the second equation is supposed to be the input for that equation.

Re: Question L.35
I got 3FeBr2 + 3Na2CO3 = 6NaBr + 3CO2 + Fe3O4 for balancing the equation. I started with the Fe and then did the Br and then the Na and then the C and O.

Re: Question L.35 [ENDORSED]
Hello!
Dr. Lavelle posted on his website something titled “Solution Manual Errors 7th Edition”. I would suggest that you could look over these and if there is anything that seems kind of off, you can always look at it for reference. For L.35, he posted that the book messed up and FeBr2 needs to be Fe3Br8.
Best,
Rita

Re: Question L.35
My equations are
Fe + Br 2 -> FeBr2
3FeBr2 + Br2 -> Fe3Br8
Fe3Br8 + 4Na2CO3 -> 8NaBr + 4CO2 + Fe3O4
Assuming that the question was written incorrectly
Fe + Br 2 -> FeBr2
3FeBr2 + Br2 -> Fe3Br8
Fe3Br8 + 4Na2CO3 -> 8NaBr + 4CO2 + Fe3O4
Assuming that the question was written incorrectly

Re: Question L.35
Does anyone know how to finish this problem after balancing the equations? Thank you!

Re: Question L.35
For the rest of the problem, you can see that from all of the balanced equations, for every 8NaBr to be produced, 3Fe is needed. You can then start with the dimensional analysis. First convert the ton of NaBr to grams, then use molar mass to get the number of moles in 2.5ton of NaBr. Then you can use the ratio of NaBr to Fe to get the moles of Fe. From there, you could use molar mass and unit conversion to calculate and convert the final mass of Fe needed. Hope this helped!
