* Lithium oxide: Li₂O
* Chlorine gas: Cl₂
* Aluminum bromide: AlBr₃
These compounds don't react together to form a single, new compound. They are separate entities.
If you're interested in a reaction between these compounds, you would need to specify the specific reaction you're interested in. For example, you might want to know what happens when lithium oxide reacts with chlorine gas, or aluminum bromide reacts with chlorine gas.
Let me know if you have a specific reaction in mind, and I can help you with the chemical equation!
