The system described by the reaction: CO(g) + Cl2(g) m COCl2(g) is at equilibrium at a given temperature when PCO = 0.30 atm, PCl2 = 0.10 atm, and PCOCl2 = 0.60 atm. An additional pressure of Cl2(g) = 0.40 atm is added. Find the pressure of CO when the system returns to equilibrium.
Electron Configuration tells us where an atom’s electrons are (which specific atomic orbitals) helps us predict chemical reactivity of electrons and structures of compounds Aufbau Principle: Electrons fill the lowest energy orbitals first in the ground state Electrons are lazy and build up from the bottom Pauli Exclusion Principle: No two electrons in the same atom can have the same quantum numbers This means a maximum of 2 electrons per single orbital Hund’s Rule: Electrons do not begin to pair in orbitals of the same energy until each orbital has 1 electron of the same spin Diamagnetic: 0 unpaired electrons Paramagnetic: At least 1 unpaired electron A condensed electron configuration has the element symbol of the pervious noble gas
