3fe+4h2o(yields) fe3o4+4h2. what is the mole ratio of fe3o4 to fe?

a- 1: 3
b- 1: 4
c- 3: 1
d- 4: 3

A- 1:3

Explanation:

Mole ratio is the ratio between the amount (In moles) of two substances involved in a chemical reaction.

For the reaction:

3Fe + 4H₂O → Fe₃O₄ + 4 H₂

There is 1 mole of Fe₃O₄ per 3 moles of Fe. In other words, the mole ratio of Fe₃O₄ to Fe is 1:3. Thus, answer is:

A- 1:3
