The balanced chemical equation for the reaction between lithium oxide (Li₂O) and sulfur dioxide (SO₂) is:

Li₂O + SO₂ → Li₂SO₃

This reaction produces lithium sulfite (Li₂SO₃).

Here's a breakdown of the balancing process:

* Li₂O: There are two lithium atoms (Li) and one oxygen atom (O) on the left side.

* SO₂: There is one sulfur atom (S) and two oxygen atoms (O) on the left side.

* Li₂SO₃: There are two lithium atoms (Li), one sulfur atom (S), and three oxygen atoms (O) on the right side.

To balance the equation, we need:

* Two Li₂O molecules on the left side to provide two sulfur atoms and four oxygen atoms.

* One SO₂ molecule on the left side to provide one sulfur atom and two oxygen atoms.

This results in the balanced equation:

2 Li₂O + SO₂ → 2 Li₂SO₃
