Mountains that begin when molten material reaches earth’s surface through a weak area of crust are fault-blocked mountains.

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

What reaction is taking place? 02 + c3h8 = h20 + co2
