Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb2+ + 2cl -, the concentration of the products yields a value of 2.1 x 10-2: precipitation will occur. precipitation will not occur.

Yes, Precipitation will occur.

Explanation:

The solubility product of salt =

Ionic product of the salt =

 Precipitation

No Precipitation

Precipitation of salt occurs when its ionic product exceed sits solubility product.So, here in this case lead chloride's ionic product is greater than that of its solubility product which means that  precipitation will occur. .

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
