The balance form of the equation is given below.
Pb(NO3)2+2KI ——-> 2KNO3 + PbI2
Explanation:
In this equation lead nitrate and potassium iodide are reactants while potassium nitrate and lead iodide are the products. In the unbalanced form of equation, two molecule of iodine are formed in the product whereas there is only one molecule of iodine is present in the reactant. So for balancing this, 2 value is put in front of potassium iodide but by putting 2, potassium is also double in the reactant so 2 is also placed in front of potassium nitrate in the product and the equation is balanced.
