Final answer:
There is no reaction between potassium nitrite and ammonia under normal conditions, and hence no net ionic equation for KNO2 + NH3 can be provided.
Step-by-step explanation:
The net ionic equation KNO2 + NH3 assuming reaction with ammonia and potassium nitrite is not provided directly in your question or examples. However, if you're asking for the reaction that occurs when potassium nitrite reacts with ammonia in water, the reactants would first dissociate into their respective ions in the aqueous solution. Potassium nitrite (KNO2) dissociates into K+ and NO2- ions, while ammonia (NH3) reacts with water to form NH4+ and OH- ions. You can then write the net ionic equation by removing the spectator ions and representing only the ions that participate in the reaction.
However, note that NH3 reacts with H2O in a reversible reaction, where NH3 is a weak base:
NH3(aq) + H2O(l) ⇌ NH4+ (aq) + OH-(aq)
This equilibrium would not typically react with the ions produced by the dissociation of KNO2 in water since we do not have a strong acid or base that can shift the equilibrium significantly. No reaction seems to occur between NH3 and KNO2 under normal conditions, so no net ionic equation can be written.
