Aqueous potassium bromide reacts with aqueous silver nitrate AgNO3 to form aqueous potassium nitrate KNO3 and solid silver bromide. Write a balanced chemical equation for this reaction.

KBr (aq) + AgNO3 (insert arrow) KNO3 (aq) + AgNr (s)

The balanced chemical equation for the reaction is as below

KBr (aq) + AgNo3 → KNO3 (aq) + AgBr (s)

Explanation

from the equation above the stoichiometric coefficient before KBr is 1, before AgNo3 is 1, before KNO3 is 1 and before AgBr is also 1. Therefore 1 mole of KBr reacted with 1 mole of AgNO3 to form 1 mole of KNO3 and 1 mole of AgBr.
