Transcript of General Chemistry: A Structural Approach

General Chemistry:
A Structural Approach Why structure? More focus on concepts Part 1:
From Atoms to Molecules Part 2:
From Molecules to Matter Part 3:
From Matter to Chemistry Math is less of a barrier to entry Less emphasis on rote memorization The traditional approach is highly focused on providing "Cheminess" at the start instead of delivering a more philosophically consistent experience. "Cheminess"? Periodic table properties come from how atoms are built. A little algebra appears with isotope ratios first, then again with the mole, picks up again with algebraic balance, and thermo and gas laws... Behavior is a function of structure. Many questions can be answered by thinking about the underlying structure. Memorization is reserved for polyatomic ions and execptions to electron configuration rules. Reading isotope symbols Electrons, protons, neutrons
and isotope ratios* Orbitals, quantum numbers and Aufbau The periodic chart and periodic properties Types of bonding, bonds and hybridization The valence concept Nomenclature and binary compounds Lewis structures VSEPR Theory Atomic Structure Molecular Structure The Mole Concept Measurement & units Percent composition Avogadro's Number Empirical & Molecular
Formula Nanoscale can go here... Between molecules and (common) matter Concepts of size and impact on properties Examples of nano in the lab Examples of nano in consumer products Examples of nano & analytical overlap Gases, Ideal and Real Thermodynamics Empirical gas Laws:
Avogardro, Boyle, Charles, and Dalton The Ideal Gas Law The Van der Waals
Equation of State Kinetic Molecular Theory Work & Heat Hess' Law Energy & Enthalpy The three laws of thermodynamics Entropy & Free Energy Reaction Control: Spontaneity, Standard States and LeChatelier's Principle Reactions Reaction types and basic balancing Limiting reagents Redox half-reaction balance method Algebraic balancing Solutions and Phases "Cheminess," is like "Truthiness." It has the look and feel of the real thing without actually being the real thing. Chemistry is the study of the organization and manipulation of matter. Structure matters. Philosophically consistent? Structure implies Function Properties Behavior
