Answer:

SeCl₆ + O₂ → SeO₂ + 3Cl₂

Explanation:

Unbalanced:

SeCl₆ + O₂ → SeO₂ + Cl₂

Count the atoms.

On the left side, we have 1 Se atom, 6 Cl atoms, and 2 O atoms.

On the right side, we have 1 Se atom, 2 O atoms, and 2 Cl atoms.

So everything is balanced except for Cl. To balance, we put a 3 coefficient in front of Cl₂.

SeCl₆ + O₂ → SeO₂ + 3Cl₂
