Question

hydrocyanic acid express your answer as a chemical formula.

Explanation:

Step1: Recall the composition of hydrocyanic acid

Hydrocyanic acid consists of a hydrogen ion (\(H^+\)) and a cyanide ion (\(CN^-\)).

Step2: Combine the ions to form the formula

To form a neutral compound, the positive charge of \(H^+\) and the negative charge of \(CN^-\) balance each other. So the formula is \(HCN\).

Answer:

\(HCN\)
