The prelim will cover Chapters 1 5 and 8. The prelim will have 1-5 8 a periodic table with molar masses and a table of possibly relevant constants. Know the essential equations from memory: λν = c, ε = hν, E(n) = -RHZ2/n2, ΔE = Efinal – Einitial, KE = ½ mv2, d = m/V, concentration (M) = moles/liter of solution [ C = m/V] calculate m/V], molecular masses, etc. Same for concepts and “rules”: solubility, balancing redox rules : equations, names of polyatomic ions, acid/base, wavelengths for visible light, orbital names, quantum numbers, nodes, etc.
