Unformatted text preview: What are the equations that go with them? 1. Energy is conserved deltaE=q+w 2. The entropy of the universe is always increasing deltaS(uni)=deltaS(syst)+deltaS(surr) > 0 3. The entropy of a pure crystalline solid at absolute zero is zero. S=kLnw A solution of NaF is added drop wise to a solution that is .0144 M Ba2+. When the concentration of F- exceeds ____________ M, BaF2 will precipitate. Neglect volume changes, for BaF2 Ksp=1.7E-6 Write Ksp expression Plug in known values, solve for [F-] Answer: 1.1E-2 M...
