Question

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

Answer 1

anser is A

Explaination

Answer 2

A) 6.

Step-by-step 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.
