Question

is this chemical equation \balanced\ or \unbalanced\?
4fe + 3o₂↑ 2fe₂o₃
○ balanced
○ unbalanced

Explanation:

Step1: Count atoms on left - hand side

• For Fe: There are 4 Fe atoms.
• For O: In \(O_2\), if we consider the coefficient 3, the number of O atoms is \(3\times2 = 6\).

Step2: Count atoms on right - hand side

• In \(2Fe_2O_3\), for Fe: \(2\times2=4\) Fe atoms.
• For O: \(2\times3 = 6\) O atoms.

Since the number of Fe and O atoms is the same on both sides of the equation \(4Fe+3O_2
ightarrow2Fe_2O_3\).

Answer:

Balanced
