1) K2C O3 + HNO3= ... + ... + COz^

The reaction you're referring to involves potassium carbonate (K2CO3), ozone (O3), and nitric acid (HNO3). When these react, you generally get potassium nitrate (KNO3), carbon dioxide (CO2), and water (H2O) as products.

The balanced equation would be:

\[ K2CO3 + 2 HNO3 + O3 \rightarrow 2 KNO3 + CO2 + 2 H2O \]

So, the products are potassium nitrate (KNO3), carbon dioxide (CO2), and water (H2O).
