Question

1. al₂s₃ → al + __ s

1 al₂s₃ → 2 al + 3 s

Explanation:

Step1: Balance Al atoms

In \(Al_2S_3\), there are 2 Al atoms. So, we put a coefficient of 2 in front of Al on the right - hand side.

Step2: Balance S atoms

In \(Al_2S_3\), there are 3 S atoms. So, we put a coefficient of 3 in front of S on the right - hand side.

Answer:

\(1Al_2S_3
ightarrow2Al + 3S\)
