Question

question #1 - use the balanced equation to answer the following question. identify the coefficient of aluminium oxide (al₂o₃). 4 al + 3 o₂ → 2 al₂o₃ options: 1, 2, 3, 4

Explanation:

Step1: Locate $\text{Al}_2\text{O}_3$ in equation

Find the term $\text{Al}_2\text{O}_3$ in $4\text{Al} + 3\text{O}_2
ightarrow 2\text{Al}_2\text{O}_3$

Step2: Identify its leading coefficient

The number before $\text{Al}_2\text{O}_3$ is 2.
