Identify the solid remaining when each of the following is heated.

(a) lithium trioxonitrate (V);
(b) potassium trioxonitrate (V);
(c) calcium trioxonitrate (V);

4 LiNO3 → 2 Li2O + 4 NO2 + O2

2 KNO3 ↔ 2 KNO2 + O2
2 Ca(NO3)2 → 2 CaO + 4 NO2 + O2

Who named those compounds? Those are not the correct names. Also, you didn't name the solids that were produced and that was the question.
