6. balance H & O (Acidic med - O by H2O and H by H+) (Basic medium - O by H2O and H by OH-)

Aufbau - In the ground state of the atoms, the orbitals are filled in order of their increasing energies.

Pauli Exclusion - An orbital can have max two electrons and these must have opposite spins.

Hunds Rule of Maximum Multiplicity - Electron pairing in p, d, f orbitals can not occur until each orbital of a given subshell contain one electron each or is singly occupied.

Thermodynamics all formula and reactions

First law of thermodynamics = energy can neither be created nor be destroyed.

Changes in Equilibrium 

Forward reaction = Reactant more, Product less, Qc < Kc

Backward reaction = Reactant less, Product more  Qc > Kc

O2 -1 -2 +1 +2, F2 -1 -2 +1 +2, N2 -1 -2 -3 +1 +2 +3, 

metals = electron donors = self oxidation = reducing agent  = basicity 

non - metals = electron acceptors = self reduction = oxidising agent = acidity
