That is what it would be balanced, hope this helped</span>
two reasons why cryolite is used in the electrolysis of aluminium oxide. The mixture of cryolite and aluminium oxide has a lower melting point than pure aluminium oxide. This means a lower amount of energy is required to establish effective conditions for electrolysis and thus makes it more cost effective.

The answer is b sorry if wrong,
Answer:
Relative crystal field splitting of the ligands
Explanation:
The formation constant of a complex is the equilibrium constant that shows the stability of the complex. This equilibrium constant is found to depend on the identity of the central metal atom/ion and the identity of the ligands.
Some ligands are called strong field ligands while others are known as weak field ligands. Other ligands lie somewhere in between the two extremes in the spectrochemical series. The spectrochemical series arranges ligands in order of their relative magnitude of crystal field splitting. The greater the magnitude of crystal field splitting, the greater the formation constant or equilibrium constant of the complex.
Strong field ligands are able to participate in ligand to metal charge transfer or metal to ligand charge transfer as the case may be. Hence strong field ligands possess pi-orbitals which interact with metal pi orbitals.
The order of decreasing formation constant in the question reflects the relative positions of the ligands in the spectrochemical series. Ammonia is lower than ethylene diammine in the series which is also lower than a diene. A diene has pi orbitals capable of interaction with metal pi orbitals hence the highest crystal field splitting and equilibrium constant.
Answer:
H3PO4 + 3KOH---------> K3PO4 + 3H2O
Explanation
H3PO4 + KOH------------> K3PO4 + H20
when an hydrogen ion containing acid (HX) reacts with a hydroxide containing base(BOH) they produce water and a "salt".
water can be called dihydrogen oxide (H2O), but it can also be called
hydrogen hydroxide (HOH)...same thing.
so the phosphoric acid (H3PO4) contains 3 hydrogen ions (H), and needs 3
hydroxide ions to from 3 hydrogen hydroxides .. that is 3 waters AND A "SALT" WITH THE REMAINING SPECIES ( K AND PO4)
so let us balance
H3PO4 + 3KOH--------->K3PO4 + 3HOH or
H3PO4 + 3KOH---------> K3PO4 + 3H2O
Check:
6 H on the left side, 6 H on the right side
1 P on the left side, 1 P on the right side
3 K on the left side, 3 K on the right side
7 O on the left side, 7 O on the right side
abadabaabdabadaba........that's all folks
yup it is balanced
