multiple choice\nquestion 4\nwhat best describes the equation below?\nfe + o₂ → fe₃o₂\na balanced\nb unbalanced
Answer
# Answer:
B. Unbalanced
# Explanation:
## Step1: Count Fe atoms
Left side: \(1\) Fe atom. Right side: \(3\) Fe atoms.
## Step2: Count O atoms
Left side: \(2\) O atoms. Right side: \(2\) O atoms.
Since the number of Fe atoms is not the same on both sides, the equation is unbalanced.
