Study Topics for Exam 4 From Chapters 4,5,8

Chapter 4 Solution Chemistry Solute in Solvent yields Solution (solubilities) Strong vs. Weak Electrolytes Arrhenius Acids & Bases (strong vs. weak) Net Ionic Reactions (ppt, gas, weak electrolyte) Oxidation-Reduction (ion-electron method) Molarity (n=MV) & Titration (redox & acid/base)

Chapter 5 Energy Kinetic vs. Potential Energies; Heat vs. Work Exothermic vs. Endothermic Heat Capacity,  E = C V  T while  H = C P  T Enthalpy,  H = heat of reaction State Functions and Hess’s Law  H =  n products  H f ° -  n reactants  H f °

Chapter 10 Gases Ideal Gas, PV = nRT (vs. Real Gases) – PV fixed if (n,T) fixed (Boyle’s Law) – V/T fixed if (n,P) fixed (Charles’s Law) – V/n fixed if (P,T) fixed (Avogadro’s Law) Gas Reaction Stoichiometry Kinetic Theory Consequences – P =  P i (Dalton’s Law) total = sum of partial pressures – v 1 /v 2 = (m 2 /m 1 ) ½ (Graham’s Law)
