H2 + Fe3O4 -> Fe + H2O first locate out what we've on both aspect so... Left aspect: Hydrogen (h) = 2 Iron (Fe) = 3 Oxygen (o) = 4 excellent aspect: (h) = 2 (Fe) = a million (o) = a million So first nicely handle the iron (Fe) cos thats the finest. when you consider that there are 3 circumstances as many (Fe)s on the left are there are on the right, placed a three in the front of the (Fe) on the right. this provides us: H2 + Fe3O4 -> 3Fe + H2O now on both aspect we've: Left aspect: Hydrogen (h) = 2 Iron (Fe) = 3 Oxygen (o) = 4 excellent aspect: (h) = 2 (Fe) = 3 (o) = a million so now shall we style the (o). there are 4 circumstances as many on the left, so nicely have the multply the (o)s on the right by using 4. so we get: H2 + Fe3O4 -> 3Fe + 4H2O we've now the oxygens looked after out, yet in doing so we've inadverdatly given ourself too many (h)s. there are literally 4 circumstances as many (h)s on the right, so we will only multiply the (h)s on the left by using 4. so the only excellent equation is: 4H2 + Fe3O4 -> 3Fe + 4H2O. the cooeficent is only the large style in the front, and that is 4. sorry if u didnt favor all that, only concept identity ascertain =P answer is 4.

3Fe + 4H2O = Fe3O4 + 4H2
The (g) does mean gas.

3Fe+4H2O->Fe3O4+4H2 'g' means gaseous state

hmm. i think the (g) means gas.
good luck balancing it!
