FREE MEDAL IF YOU CAN ANSWER THIS AND A FAN TOO!!!!
solid iron (III) hydroxide decomposes to produce iron (III) oxide and water vapor

Answer 1

@abb0t @amistre64

Answer 2

this doesnt sound like a question to me

Answer 3

is stoicheometry is supposed be converted from words to actual elements and then balanced

Answer 4

Ok, so write it down :)
Iron (III) oxide = Fe\(_2\)O\(_3\)
Decomposes to Iron (III) and water vapor...
Are you sure its water vapor? Are you sure it says water vapor?

Answer 5

I'm assuming this is done in aqueous solution then.

Answer 6

i wouldnt know how to notate the elements, i can balance an equation sometimes .. but the chem notation is not my area

Answer 7

water vapor is H2O

Answer 8

Fe\(_2\)O\(_3\) \(\sf _{(aq)}\)

Answer 9

aqueous means that the solvent is water, which is what is breaking down the molecule.

Answer 10

i think this is how its supposed to look but i need it balanced Fe(OH)->Fe + H2O

Answer 11

Well, I already gave you the formula for iron (iii) oxide up above. Please read what I wrote.

Answer 12

but my teacher said hydroxide is (OH)

Answer 13

Even though it should be YOU who should be writing the formula down since this is YOUR homework.
I don't need to learn this, you do.

Answer 14

Oh, you're right. I messed up. i misread.
hydroxide for oxide. I'm sorry.

Answer 15

But either way, your formula is still wrong :)

Answer 16

its cool so i just switch the charges on both sides?

Answer 17

Do you understand what decomposition means? It means to break down the molecule into simpler ones.

Answer 18

thats what she typed on the paper and gave us lol

Answer 19

so do i just leave it blank and tell her she is wrong tommorow?

Answer 20

She wrote Fe(OH) \(\rightarrow\) Fe\(^{3+}\) + H\(_2\)O
as the final answer?

Answer 21

yep

Answer 22

Yes. Then you need to take that back to her and correct her.

Iron (III) hydroxide is not what she wrote down, it is \(\sf \color{red}{Fe(OH)_3}\)

Answer 23

ok and thx for the help and sorry for the trouble ;-)
