Answer:
The balanced chemical equation for the reaction between lithium oxide and water to form lithium hydroxide is:
Li2O + H2O → 2LiOH
Step-by-step explanation:
This equation is balanced because there are the same number of each type of atom on both sides of the equation. Specifically, there are 2 lithium atoms, 2 oxygen atoms, and 2 hydrogen atoms on both sides. This is in accordance with the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Therefore, the number and type of atoms must be the same before and after the reaction.
