Determine whether a precipitate of lead chloride, PbCl2(s), will form when a 2.0 × 10−3 mol/L solution of lead nitrate, Pb(NO3)2(aq), is combined with 1.0 × 10−3 mol/L solution of hydrochloric acid, HCl(aq), in equal volumes. a. Write the equilibrium expression for PbCl2(s).
b. Ksp for PbCl2(s) is 1.6 × 10−5. Calculate the trial ion product, Q, for this reaction.
c. Will a precipitate form? Explain.

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o
