Question

its time for the unit exam. this is your opportunity to show how if you dont feel ready, you may want to stop and clarify anything over any notes you have taken and review the key terms. good luck! note: to answer some of the questions, it may help to reference a p examine the reaction equation. fe₃o₄(s) + co(g) → feo(s) + co₂(g) what coefficients will balance the equation? 3, 1, 1, 1 3, 3, 1, 1 1, 1, 3, 1 2, 2, 6, 4

Explanation:

Step1: Balance Fe atoms

$$\text{Fe}_3\text{O}_4(s)+\text{CO}(g)\to 3\text{FeO}(s)+\text{CO}_2(g)$$

Step2: Balance O atoms

$$\text{Fe}_3\text{O}_4(s)+\text{CO}(g)\to 3\text{FeO}(s)+\text{CO}_2(g)$$
Now, count O atoms on left side: \(4 + 1=5\). On right side: \(3\times1+2 = 5\).

Step3: Balance C atoms

C atoms are already balanced (\(1\) on each side).

Answer:

1, 1, 3, 1
