If you failed Exam 1 and you also fail this exam you should consider withdrawing from Chem 102. The last day to withdraw from the course is Friday November 8th. I will make sure you have your grades in time to make this decision. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Exam 3: States of Matter and Chemical Calculations Unit 6: States of Matter Read Chapter 5, sections 5.1- 5.3, Chapter 10, sections 10.1- 10.2 and 10.3 - 10.8 (solids) • list the ideal gas postulates • sketch an animation of ideal gas motion and relate the components of your model to the ideal gas postulates • identify the four variables that can be used to characterize a gas quantitatively (P, T, V and n) • describe pressure as an average Force/Area • recognize when the average force increases due to momentum changes or frequency changes • realize that the pressure of a gas is proportional to the mole number of the gas (at constant P,T,V) thus gas pressure can be used in place of mole in stoichiometry calculations • assign the proper units to each of the variables: expressing P in atm, n in moles, T in Kelvin, and V in liters and use R = 0.0821 Latm/mol K • convert among volume units (milliliter, liter, cm3); pressure units (torr, atm, kPa); and temperature units (C and K) • be able to draw particle diagrams that distinguish gas and liquid phases; be able to describe the motion in the phases • accurately describe vapor pressure and...
