a. answer is 3. and b. answer is 2

It is correct?

Answer 1

Hi Ooyeon,

There are a few typos in comparison between your equation and the questions. It makes sense to me that it is KClO₃ as the chlorate anion has a -1 charge that would be balanced out with potassium K. Then in the questions you write C1O3. On my keyboard 1 and L are far apart so I don't if that is a typo. The carbonate anion CO₃^-2 has a -2 charge that would be balanced out by 2 K only.

I just wanted to point this out for future reference, because I know it is the chlorate anion since the product are KCl and O₂. But yes you are correct in your answers. Do you understand the concept well?
