How is energy related to the change of state represented by the model? atoms gain energy as a solid changes to a gas. atoms gain energy as a liquid changes to a gas. atoms lose energy as a solid changes to a gas. atoms lose energy as a liquid changes to a gas.

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.
