which of the following correctly pair the polyatomic ion with its formula? select all that apply. select all that apply: cyanide, cn⁻ chlorate, clo₃⁻ sulfate, so⁻ nitrate, no₃⁻

Answer

Answer:

  • A. cyanide, $CN^-$
  • B. chlorate, $ClO_3^-$
  • D. nitrate, $NO_3^-$

Explanation:

Step1: Recall cyanide ion

The cyanide ion is a well - known polyatomic ion with the formula $CN^-$.

Step2: Recall chlorate ion

The chlorate ion has the formula $ClO_3^-$.

Step3: Recall sulfate ion

The correct formula for the sulfate ion is $SO_4^{2 -}$, not $SO^-$. So the sulfate option is incorrect.

Step4: Recall nitrate ion

The nitrate ion has the formula $NO_3^-$.
