균형 맞추기. Fe3O4 + H2 → Fe + H2O

균형 맞추기. Fe3O4 + H2 → Fe + H2O

Fe3O4(s) + H2(g) → Fe(l) + H2O(g)

aFe3O4 + bH2 → cFe + dH2O

 

 

Fe: 3a = c ... (1)

O: 4a = d ... (2)

H: 2b = 2d ... (3)

 

 

a = 1 이라 두면,

from (1), c = 3

 

from (2), d = 4

 

from (3), b = 4

 

 

답: Fe3O4 + 4H2 → 3Fe + 4H2O

Fe3O4(s) + 4H2(g) → 3Fe(l) + 4H2O(g)
