Question

Pb(NO3)2 + KI— Pbl2 + KNO3

Answer 1

Pb(NO₃)₂ + 2KI —> Pbl₂ + 2KNO₃

Step-by-step 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
