Question

complete the following table: some polyatomic ions name peroxide anion acetate anion carbonate anion hydronium cation chemical formula

Explanation:

Step1: Recall peroxide anion formula

The peroxide anion has a chemical formula of $O_2^{2 -}$.

Step2: Recall acetate anion formula

The acetate anion has a chemical formula of $CH_3COO^-$.

Step3: Recall carbonate anion formula

The carbonate anion has a chemical formula of $CO_3^{2 -}$.

Step4: Recall hydronium cation formula

The hydronium cation has a chemical formula of $H_3O^+$.

Answer:

Peroxide anion: $O_2^{2 -}$
Acetate anion: $CH_3COO^-$
Carbonate anion: $CO_3^{2 -}$
Hydronium cation: $H_3O^+$
