lower
Diamagnetic?
all e- paired not magnetic
Molecular
Low Melting points ( VVan der wals interactions)
Determined experimentaly

deltE=q + -PdeltV (-Pdeltv=W)
in gas Expansion and compression are?
Expansion= -W Compression= +W
Bond Enthalpies calcs?
Bonds Broken - Formed
Enthalpy of formation?
Product-Reactant, Elements =0,
Formation RXN?
Reactants must all be in standard states, only 1 Mole Product
Gibbs Eq?

To solve Gibbs Temp ?’s @ Equilibrium
Set G to 0 and solve or -T w/ given s & H
Strong Acids
HCL, HBR,HI, HNO3, HCLO3, HClO4, H2SO4
Gases More soluble @
