Question

what is the name of the compound with the formula baso3? what is the name of the compound with the formula kno2?

Explanation:

In chemistry, naming of compounds follows certain rules. For $BaSO_3$, barium ($Ba^{2 + }$) is the cation and sulfite ($SO_3^{2 - }$) is the anion, so it's named barium sulfite. For $KNO_2$, potassium ($K^+$) is the cation and nitrite ($NO_2^-$) is the anion, so it's named potassium nitrite.

Answer:

The compound with formula $BaSO_3$ is barium sulfite.
The compound with formula $KNO_2$ is potassium nitrite.
