Again this is a question about bonding. Hint: Can you tell me which three compounds are salts? (They are the one with the ionic bonds.)

Actually it's $\displaystyle H_2S$. To the best of my knowledge $\displaystyle ZnC0_3$ is a salt formed from $\displaystyle Zn(OH)_2$ (a base) reacting with $\displaystyle H_2CO4$ percarbonic acid. Acid + Base = Salt + water.
