General principle of solubility is 'like dissolves like'

is an ionic compound, wherein the constituent ions (

and

) are held by electrostatic forces of interaction.
Such ionic compounds are soluble in polar solvents.
Among the solvent mentioned in question, water (

) has maximum polarity. Hence,

is most likely to dissolve in
Answer:
<em>Mass percent composition of K = mass contribution of K/molecular mass of K3Fe(CN)6 x 100% Mass percent composition of K = 117.30 g/mol/329.27 g/mol x 100% Mass percent composition of K = 0.3562 x 100% Mass percent composition of K = 35.62%</em>
2H2 + O2 = 2H2O since two elements created a compound, in this case water.
