Question

aqueous potassium nitrate and solid silver bromide are formed by the reaction of aqueous potassium bromide and aqueous silver nitrate. write a balanced chemical equation for this reaction. kno₃(aq) + agbr(s) → kbr(aq) + agno₃(aq)

Explanation:

Step1: Identify reactants and products

Reactants are aqueous potassium bromide ($KBr(aq)$) and aqueous silver nitrate ($AgNO_3(aq)$). Products are aqueous potassium nitrate ($KNO_3(aq)$) and solid silver bromide ($AgBr(s)$).

Step2: Write the un - balanced equation

$KBr(aq)+AgNO_3(aq)
ightarrow KNO_3(aq) + AgBr(s)$

Step3: Check the balance of atoms

On both sides, there is 1 potassium (K), 1 bromine (Br), 1 silver (Ag), 1 nitrogen (N) and 3 oxygen (O) atoms. So the equation is already balanced.

Answer:

$KBr(aq)+AgNO_3(aq)
ightarrow KNO_3(aq) + AgBr(s)$
