question
identify the formula for permanganic acid.
answer
h₂mno₄
hmno₄
hmno
you were sure and incorrect h₂mno
i dont know yet

Explanation:

Step1: Recall acid - naming rules

In oxyacids, permanganic acid has manganese in its highest oxidation state in the $MnO_4^-$ poly - atomic ion. The charge on the $MnO_4^-$ ion is - 1.

Step2: Determine the formula

To balance the - 1 charge of the $MnO_4^-$ ion, one hydrogen ion ($H^+$) is needed. So the formula of permanganic acid is $HMnO_4$.

Answer:

$HMnO_4$
