The balanced equation of for the above reaction is as follows;
2KOH + H₂SO₄ ---> K₂SO₄ + 2H₂O
stoichiometry of KOH to H₂SO₄ is 2:1
the number of KOH moles reacted - 0.124 mol/L x 0.046 L = 0.0057 mol
for complete neutralisation the base should react with acid in 2:1 molar ratio
if 2 mol of KOH reacts with 1 mol of H₂SO₄
then 0.0057 mol of KOH reacts with - 1/2 x 0.0057 mol = 0.0029 mol
the number of H₂SO₄ moles in 28.1 mL - 0.0029 mol
Molarity is number of H₂SO₄ moles in 1 L
therefore number of H₂SO₄ moles in 1 L - 0.0029 mol / 0.0281 L = 0.103 M
molarity of H₂SO₄ is 0.103 mol/L

What is the formula of the hydride formed by germanium?
Nadusha1986 [10]

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 GeH_4 molecule which is stable in nature.

Hence, GeH_4 is the formula of the hydride formed by germanium.
