Final answer:
When cesium oxide reacts with water, it produces cesium hydroxide, a strong base. The balanced chemical equation for this synthesis reaction is: Cs2O + H2O → 2CsOH.
Step-by-step explanation:
When cesium oxide (Cs2O) reacts with water (H2O), the predicted products are cesium hydroxide (CsOH). This reaction is a type of synthesis reaction where an oxide reacts with water to form a hydroxide. Since cesium is an alkali metal, its oxide forms a strong base upon reacting with water. The balanced chemical equation for the reaction is:
Cs2O(s) + H2O(l) → 2CsOH(aq)
