Answer
Pb(NO₃)₂ + 2KI —> Pbl₂ + 2KNO₃
Explanation
Given unbalanced equation:
Pb(NO₃)₂ + KI —> Pbl₂ + KNO₃
Step 1: Balance the K atom on both sides by putting 2 as the coefficient of KI and KNO₃ on the reactant and product sides respectively.
Pb(NO₃)₂ + 2KI —> Pbl₂ + 2KNO₃
All atoms are the same on both sides. Hence, the balance equation is:
Pb(NO₃)₂ + 2KI —> Pbl₂ + 2KNO₃
