What are the products of the double-replacement reaction between potassium bromide and silver nitrate? Name the resulting compounds.

Verified Answer :

silver nitrate is AgNO3 potassium bromide is KBr 
Each ion has single charge whether +ve or -ve. 
AgNO3(aq) + KBr(aq) = AgBr(s) + KNO3(aq) 
AgBr is water insoluble so precipitates. Potassium nitrate is soluble so stays in solution so can also be written as K+(aq) + NO3-(aq)

nitrogen and oxygen is the answer
