Answer : YES, The precipitation reaction will occur.
Explanation : When we mix the aqueous solutions of Lead chloride and Ammonium sulfide a reaction will occur which is stated below :
![PbCl_{2} +(NH_{4}) _{2} S ----\ \textgreater \ PbS + 2[ (NH_{4})Cl]](https://tex.z-dn.net/?f=PbCl_%7B2%7D%20%2B%28NH_%7B4%7D%29%20_%7B2%7D%20S%20----%5C%20%5Ctextgreater%20%5C%20%20PbS%20%2B%202%5B%20%28NH_%7B4%7D%29Cl%5D%20)
The major product that is formed is Lead sulfate which is black in colour.
Once the reaction is complete one can observe a black precipitate getting obtained.

Answer: 0.113 moles of NaCl are created as a result of decomposing 12 grams of .
Explanation:
To calculate the moles :
The balanced chemical equation for decomposition of is:
According to stoichiometry :
2 moles of give = 2 moles of
Thus 0.113 moles of give =
of
Thus 0.113 moles of NaCl are created as a result of decomposing 12 grams of .
