Question

type the numbers that will balance this equation. if no number is required type a 1 in that blank. fe(s) + o₂(g) → fe₂o₃(g)

Explanation:

Step1: Balance oxygen atoms

Let the coefficients be \(x\) (for \(Fe\)), \(y\) (for \(O_2\)) and \(z\) (for \(Fe_2O_3\)).
The equation is \(xFe + yO_2
ightarrow zFe_2O_3\).
For oxygen: \(2y = 3z\). Let \(z = 2\), then \(2y=3\times2\), so \(y = 3\).

Step2: Balance iron atoms

For iron: \(x=2z\). Since \(z = 2\), then \(x=4\).

Answer:

4, 3, 2
