U Question 2
Consider the following reaction:
Pb(NO3)2 (aq) + 2NaCl (aq) --> PbCl2 (s) + 2NaNO3 (aq)
How many mL of 0.822 M Pb(NO3)2 are required to fully react with 35.3 mL of 0.745 M NaCl?

What effect might melting sea ice have for people who live in coastal areas?

Select all that apply. using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 (s) pb+2(aq) + 2cl -(aq). the concentration of the products yield a ksp of 2.1 x 10-2:
