what is the difference between a strong acid and a week acid??

Strong acids are those that are completely ionized in body fluids, and weak acids are those that are incompletely ionized in body fluids.

balance the following equation

K4Fe(CN)6 + H2SO4 + H2O = K2SO4 + FeSO4 + (NH4)2SO4 + CO

K4Fe(CN)6 + 6 H2SO4 + 6 H2O = 2 K2SO4 + FeSO4 + 3 (NH4)2SO4 + 6 CO

What is the magnitude of Ka?

This indicates the tendency of the acid to ionize in water
