Balance Cr(OH)4- to CrO4^2-

Different isotopes indicate that an element will have different numbers of

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.

The number at the end of an isotope’s name is the number.
