By the end of the semester, you should have mastered these concepts : 1) Stoichiometric calculations (moles, yield, limiting reactant, balancing equations) ) n understanding of the structure of atoms (nucleus arrangement of electrons 2) An understanding of the structure of atoms (nucleus, arrangement of electrons in orbitals). 3) Elements have predictable properties based on their placement in the periodic table (electron configurations). 4) An understanding of covalent versus ionic bonding and the properties ssociated with covalent versus ionic compounds associated with covalent versus ionic compounds. 5) How molecules are constructed (bonding patterns, shapes of molecules, overlap of orbitals, resonance, single/double/triple bonds) 6) Properties and behaviors of gases, liquids and solids (intermolecular forces) 7) Thermodynamics of reactions: why some reactions occur and others don’t 2 )y y occur; whether reactions give off or absorb heat; the importance of disorder
