Answer:

Explanation:

Cyanide's formula can be found either on google on on a reference table at the "polyatomic ions" table. Hydrogen, H, has a charge of 1+ when bonded, and cyanide has a charge of 1- overall, so they will be in a one to one ratio while bonded. As such, the equation is HCN.

Conjugate base of Propanoic acid ( $CH_{3}CH_{2}COOH$ is propanoate where -COOH group gets converted to -CO $O^{1-}$ . The structure of conjugate base of Propanoic acid is shown in the diagram.

The $p^{H}$ above which 90% of the compound will be in this conjugate base form can be determined using Henderson's equation as propanoic acid is weak acid and it can form buffer solution on reaction with strong base.
