What are the products when lithium reacts with water?

Explanation:
When a Group 1 metal like lithium meets water, it donates its single outer electron to form a metal hydroxide and releases hydrogen gas. The reaction shows lithium hydroxide in solution and hydrogen gas as the products. The balanced form is 2 Li + 2 H2O → 2 LiOH + H2. So the products are lithium hydroxide and hydrogen. The other possibilities would involve oxygen or carbon dioxide reacting with lithium, which isn’t what happens when lithium reacts with just water.
