Title: Which polyatomic ion contains the greatest number of oxygen atoms? Post by: lex on Sep 4, 2012 Which polyatomic ion contains the greatest number of oxygen atoms?
1. Acetate 2. Carbonate 3. Hydroxide 4. Peroxide Title: Which polyatomic ion contains the greatest number of oxygen atoms? Post by: Fisk71 on Sep 4, 2012 Just look at their formulas.
Acetate has two oxygen atoms Carbonate has three Hydroxide has one Peroxide has two. Therefore, Carbonate has the most oxygen atoms. Title: Which polyatomic ion contains the greatest number of oxygen atoms? Post by: soder253 on Sep 4, 2012 1) Acetate/Etanoate - CH3COO- 2 oxygen atoms
2) Carbonate - CO3 2- 3 carbon atoms 3) Hydroxide - OH- 1 carbon atom 4) Peroxide - O2 2- 2 carbon atoms Carbonate - CO3 2- has the most oxygen atoms so 2) is your answer |
