The equation Ge + 2H2O -> Ge(OH)4

1. The above chemical equation describes the reaction process between Germanium (Ge) and water (H₂O), resulting in Germanium Hydroxide (Ge(OH)₄).

2. Reaction conditions: For the reaction to occur, Ge needs to be dissolved in water at high temperature and under high pressure conditions.

3. Reaction process: When Ge is exposed to water at high temperature and pressure, it reacts with water, leading to the formation of Ge(OH)₄.

4. Occurrence phenomena: During the reaction, changes in color and volume of the liquid can be observed. Sometimes, gas bubbles may be seen escaping from the liquid.

Note: This is just general information about this type of reaction and there may be differences in details depending on the specific conditions of each particular reaction.
