CHEMISTRY

Below is how the units are divided on CHEMDUNN:

Unit 1. Measurement and Observation

Learn the basic skills and equipment that will be required for this course.  To be discussed: lab safety and equipment, introduction to matter, significant figures, measuring devices, dimensional analysis, density, and volume.    VISIT UNIT 1 PAGE

Unit 2. Gases

Gases were one of the first states of matter that early scientists studied in depth and proposed explanations from empirical evidence. Following in their footsteps, we too shall get a taste of the behavior of gases first.  To be discussed: gas relationships, diffusion, kinetic molecular theory, particle level diagrams, and gas behavior.    VISIT UNIT 2 PAGE

Unit 3. Atomic Structure

The atom is central to the study of chemistry.  The atom is the smallest unit of matter that retains all the chemical properties of an element.  Understanding the atom and the elements that will be seen throughout the course will provide a foundation to build from to understand how these particles combine and react.  To be discussed: atomic structure history, isotopic notation, quantum mechanics, electron configuration, emission spectroscopy, periodic table, and atomic trends.     VISIT UNIT 3 PAGE

Unit 4. Bonding and IMFs

After learning about the atom we look towards when two or more atoms combine to form a compound. The nature of bonding between the atoms and their subsequent shape, properties, and behaviors will be explored in this unit.   To be discussed: nomenclature, bonding, Lewis structures, VSEPR & molecular geometry, bond/molecular polarity, and intermolecular forces and attractions.       VISIT UNIT 4 PAGE

Unit 5. Types of Reactions

Understanding chemicals (compounds) and how they behave (react) when placed together is central to the study of chemistry. It is often why everyone is first drawn to the subject -- predicting if something will go boom or if all of a sudden you see a yellow solid appear.  To be discussed:  writing/balancing chemical equations, combustion reactions, single replacement, activity series, double replacement, precipitates, solubility, complete ionic and net ionic equations.      VISIT UNIT 5 PAGE

Unit 6. Mole & Stoichiometry

Atoms and molecules are so small, but chemists use a method of counting by weighing to measurement amounts. This is very useful as we see the information contained in a balanced chemical equation. This will lead us into stoichiometry: a concept that looks funny and might be scary to learn, but once you've got it you have just accomplished a major part of chemistry. To be discussed: molar ratios, mole:mole stoichiometry, limiting and excess reactants, and percent yield.       VISIT UNIT 6 PAGE

Unit 7. Stoichiometry Applications

Thus far you have been introduced many of the major areas of chemistry. Now, you will apply the concepts you've learned (or still working on) to gases and then be introduced more into solution chemistry which arguably is all around you -- but I guess that can be true about gases.  To be discussed: ideal gas law, molarity, solution chemistry, oxidation numbers, and redox reactions.      VISIT UNIT 6 PAGE

Unit 8. Acids & Bases

Acid/Base chemistry has great relevance to our world.  Many chemical around us from household products to pharmaceuticals have acid/base properties. We will learn more about the notorious acids, which everyone has heard about and the not-so-notorious bases that are just as equally important (and scary). To be discussed: Arrhenius Theory, Bronsted-Lowry Theory, acid-base strength (degree of dissociation), pH concept, pH calculation, pOH, indicators, neutralization reactions, and acid-base titration calculations and lab technique.      VISIT UNIT 8 PAGE

Unit 9. Thermochemistry

Let's end with a bang and feel the heat!  To be discussed:
