which of the following does not correctly pair the polyatomic ion with its formula? select the correct answer below: o cyanide, cn⁺ o bromate, bro₃⁻ o chlorate, clo₃⁻ o hydroxide, oh⁻
Answer
Answer:
A. cyanide, $CN^{+}$
Explanation:
Step1: Recall cyanide ion formula
The cyanide ion has a formula of $CN^{-}$, not $CN^{+}$.
Step2: Check bromate ion
The bromate ion is correctly represented as $BrO_{3}^{-}$.
Step3: Check chlorate ion
The chlorate ion is correctly represented as $ClO_{3}^{-}$.
Step4: Check hydroxide ion
The hydroxide ion is correctly represented as $OH^{-}$.
