Please type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.
It is called a BALANCED reaction, not a "balance reaction".

The bicarbonate ion from either the sodium or potassium bicarbonate will reaction with the hydrogen ions of the acid, causing the release of CO2 and the formation of a water moecule.

H+ + HCO3- --> H2O + CO2

(Na+ and K+ remain in solution)
