What's Important

Exam IV:

Chapter 8:

Sections 1 - 8: Sections 1 - 5 were covered on Exam III, so Sections 6 - 8 will be the focus on Exam IV. To do Sections 6 and 7 require an understanding of Sections 1 - 5. Section 8 is on bond energies. TO be successful doing bond energy calculations you also have to be able to do Lewis structures. Also Lewis structures are essential for everything we covered in Chapter 9.

Exam III:

Chapter 6:

Sections 1 - 9:

Note in Section 6.5 we did not discuss the quantum numbers 'l' and 'ml' although we did discuss what these quantum number represent. The 'l' quantum number represent the sublevels: s, p, d, f, etc. The 'ml' quantum number represent the number of orbitals in each particular sublevel. I will not ask you to recite a specific set of quantum numbers for an electron, but you do have to know and understand the concept of a level, sublevel and orbital.

While we did not go into significant detail on the shapes of the different subshells I will expect you to know those shapes; an 's' subshell is spherical; a 'p' subshell consists of three 'p' orbitals that dumbell shaped with two lobes; a 'd' subshell contains five 'd' orbitals four of which have a clover-leaf shape (3-d cloverleaf).

Practice Problems at the end of Chapter 6: 6.7, 6.9, 6.11, 6.13, 6.15, 6.17, 6.21a and b, 6.23, 6.25, 6.27, 6.29, 6.31, 6.47, 6.49, 6.51, 6.55, 6.57, 6.59, 6.61, 6.63, 6.65, 6.67.

Section 4.2...double replacement reactions, solubility table and ionic and net ionic equations...very important, solubility table is discussed in this section also;

Section 4.3...neutralization reactions and how to handle strong and weak electrolytes in ionic and net ionic equations. THis section also discusses gases formed in acid-base reactions.

Section 4.4...this section covers the activity series which we 'discovered' in our first web lab. The activity series is very important. We did not discuss oxidation numbers, specifically, but we did discuss how we use the periodic table to understand the charge metals and nonmetals like to have in ionic compounds.

Section 4.5 and 4.6...introduction to the concentration expression called molarity. You must be able to prepare solutions of a specific molarity and be able to use molarity in stoichiometric calculations like those discussed in Section 3.6 and 3.7.

Section 5.1...this section contains the important definitions and ideas we use in the Chapter: including kinetic and potential energy, energy units (joules), system and surroundings, and work and heat.

Section 5.2...this section introduces the first law of thermodynamics, internal energy, delta E, defines endothermic and exothermic and describes State functions.

Section 5.3...this section introduces delta H (enthalpy) and discusses the difference between internal energy (delta E) and enthalpy (delta H). discusses coffee-cup and bomb calorimetry. This section has lots of important calculations.

Section 5.4...this sections describes characteristic properties of enthalpy in chemical reactions. Those properties include that enthalpy is an extensive property, that the sign of the enthalpy depends on the way the reaction is written, and that the enthalpy of a reaction depends on the phase of the reactants and products.

Section 5.5...this section is VERY important. It introduces calorimetry by defining specific heat and heat capacity and continues with a discussion and sample problems of using OSU calorimeters to determine the heat transferred at constant pressure and bomb calorimeters to determine the heat transferred at constant volume. The first law plays anessential role in this section.

Section 5.6...Hess's Law is introduced in this section. Hess's Law states that if a reaction is carried out in a series of steps, the delta H for the reaction can be determined by summing the delta of the indivdual steps.

Section 5.7...this section extends Hess's Law and introduces enthalpies of formation for substances. This section introduces the important mathematical equation used to calculate delta H of a reaction,
