Consider the balanced equation below.
1 answer:
A. 1:3
The equation shows that 1 mol Fe_3_O4 ≡ 3 mol Fe.
∴ The mole ratio is Fe_3_O4:Fe = 1:3 .
“B. 1:4” is <em>incorrect </em>. It is the mole ratio of <em>Fe_3O_4:H_2O </em>and of<em> Fe_3O_4:H_2 </em>.
“C: 3:1” is <em>incorrect </em>. It is the mole ratio of <em>Fe:Fe_3O_4 </em>.
“D: 4:3” is <em>incorrect </em>. It is the mole ratio of <em>H_2O:Fe and of H_2:Fe </em>.
