K2CO3 (potassium carbonate) + NaHCO3 (sodium bicarbonate)

When these two compounds react, the following reaction occurs:

K2CO3 + 2NaHCO3 → 2KHCO3 + Na2CO3

As a result of this reaction, potassium bicarbonate (KHCO3) and sodium carbonate (Na2CO3) are formed.

Please note that this reaction is a simplified representation and may not accurately reflect the actual products formed. It is important to conduct a laboratory experiment to confirm the products and balance the reaction equation.
