The atoms combine to form compounds to attain stability in nature. The combination of atoms takes place by sharing of electrons between the atoms or complete transfer of electrons from one atom to another. Generally, atoms combine to complete their octet, that is to possess eight electrons in their outer most shell (noble gas configurations) except hydrogen which can attain stability by two electrons in its outer most shell.
Since germanium has 4 electrons in its outer most shell so it needs 4 more electrons to complete its octet and attains the stability. Hydrogen has 1 electron in its outer most shell and it needs only 1 electron to attain stability so, each germanium will combine with 4 hydrogen atoms and thus forming 
molecule which is stable in nature.
Hence, is the formula of the hydride formed by germanium.

Answer:
Increases, remain constant
Explanation:
In the light spectrum, the photons with a higher frequency (hence smaller wavelengths) have higher energy. The lower the energy the lower the frequency and longer the wavelengths. The intensity of light does not change the energy levels of these photons. The higher the intensity the higher the density of the photoelectrons.
Answer:
KOH
Explanation:
Chemical reaction:
2K + 2H₂O → 2KOH + H₂
Element ratio of K.
K = 1
Because only potassium is present.
Element ratio of H₂O.
2 : 1
in water ratio of element is 2 : 1 because two hydrogen and one oxygen atom present.
Element ratio of KOH
1 : 1 : 1
in KOH elemental ratio is 1 : 1 : 1 because one potassium one hydrogen and one oxygen atom are present.
Element ratio of H₂.
2
Just two atoms of hydrogen are present.
