Day 27 skills review

DAY 27, Terms to know:

Sections 10.5-10.8, 13.5-13.6 Hess’s law, standard enthalpy of formation, bond enthalpy, colligative properties, van’t Hoff factor

DAY 27, Specific outcomes and skills that may be tested on exam 4:

Sections 10.5-10.8, 13.5-13.6

• Be able to use Hess’s law and given heats of reactions to determine the heat of reaction for another reaction
• Be able to determine enthalpies of formation for elements in their standard states
• Be able to use given enthalpies of formation to determine the enthalpy of a reaction
• Given bond enthalpies, be able to determine the enthalpy of reaction for a given reaction
• Be able to use a given heat of reaction as a relationship in a conversion question
• Be able to explain WHY each of the colligative properties changes upon increasing concentration of solute
• Be able to use the formulas for the colligative properties to calculate any of the variables in the equation given the rest of the variables
• Be able to predict the van’t Hoff factor for a given solute and use it in the formulas for colligative properties
• Be able to explain WHY the van’t Hoff factors for ionic solids at higher concentrations are often less than would normally be predicted

Complete these problems outside of class until you are confident you have learned the SKILLS in this section outlined on the study guide and we will review some of them next class period.  10.45  10.47  10.49  10.55  10.57  10.59  10.63  10.65  10.67  10.71  10.75  10.77  10.79  10.85  10.93  10.95  10.135  13.63  13.67  13.69  13.75  13.77  13.79
