Question

PLEASE HELP

What is the sum of all the coefficients in this reaction when properly balanced?

Lead (II) nitrate + hydrogen sulfide yields lead (II) sulfide + nitric acid (HNO3)

Answer 1

5

Step-by-step explanation:

The properly balanced chemical equation for this is:

Pb(NO₃)₂ + H₂S → PbS + 2HNO₃

The coefficients in order are 1, 1, 1, and 2.

Therefore, 1+1+1+2=5

The sum of the coefficients added up is 5.
