The chemical formula for lithium hydroxide is LiOH and the chemical formula for iron(II) oxide is FeO.

Therefore, when lithium hydroxide reacts with iron(II) oxide, the balanced equation is:

2LiOH + FeO -> Li2O + Fe(OH)2

The chemical formula for sulfur dioxide is SO2. Therefore, when sulfur dioxide reacts with itself, the balanced equation is:

2SO2 -> 2SO2
