If you were to microwave a bowl of soup for too long and you burn your hands as you remove the bowl from the microwave, the heat transfer that would be demonstrated would be called: conduction. Conduction occurs when heat from one substance comes in contact in another substance. Just like when heat from the bowl came in contact with your hand.

Consider the given acid ionization constants. identify the strongest conjugate base.

WARRIOR [948]

The question is incomplete. Complete question is:
Consider the given acid ionization constants. identify the strongest conjugate base.
HNO2(aq) 4.6×10−4
HCHO2(aq) 1.8×10−4
HClO(aq) 2.9×10−8
HCN(aq) 4.9×10−10
.........................................................................................................................
Correct Answer: option 4: HCN(aq) 4.9×10−10

Reason:
According to Lowry and Bronsted theory of acid and base. Stronger the acid, weaker will be the conjugate base.

In present case, ionization constant is highest of HCN i.e. 4.9× $10^{-10}$ . This signifies that, it is the strongest acid. Hence, conjugate base associated with this acid (i.e. $CN^{-}$ ) is the weakest.
