Fill in the Blank 10 points Using the formula below, complete the mole ratios 4Fe+3O_(2)arrow 2Fe_(2)O_(3) Fe_(2)O_(3):Fe choose your answer... choose your answer... 4:2 2:4 2:3

To find the mole ratio of $Fe_{2}O_{3}$ to $Fe$, we need to look at the coefficients in the balanced chemical equation.<br /><br />The balanced chemical equation is:<br />$4Fe + 3O_{2} \rightarrow 2Fe_{2}O_{3}$<br /><br />From the equation, we can see that the coefficient in front of $Fe_{2}O_{3}$ is 2, and the coefficient in front of $Fe$ is 4.<br /><br />Therefore, the mole ratio of $Fe_{2}O_{3}$ to $Fe$ is 2:4.<br /><br />So, the correct answer is $2:4$.
