Respuesta :
when Ag+ is combined with Na2CO3, the substances formed are Ag2CO3 and Na+. In this case, Ag performs single substitution over the element Na to form another set of substances. There are other types of reactions like double displacement, decomposition, etc.
Answer is: yellow precipitate (Ag₂CO₃) will form. It indicate chemical (displacement) reaction happened.
Balanced chemical reaction:
2Ag⁺(aq) + Na₂CO₃(aq) → Ag₂CO₃(s) + Na⁺(aq).
Single Displacement is reaction where neutral element metal or nonmetal become an ion as it replaces another ion in a compound.
Ag₂CO₃ is salt, poorly soluble in water.
Freshly prepared silver carbonate is colourless, but the solid quickly turns yellow.
