What is the sum of the coefficients of the following balanced chemical equation? KI + Pb (NO3) 2 → KNO3 + PbI2 A) 6 B) 10 C) 18 D) 20

anser is A

Explaination

A) 6.

Explanation:

The balanced chemical equation is:

2KI + Pb (NO₃) ₂ → 2KNO₃ + PbI₂,

It is clear that 2.0 moles of KI react with 1.0 mole of Pb (NO₃) ₂ to produce 2.0 moles of KNO₃ and 1.0 mole of PbI₂.

So, the sum of the coefficients is 6.
