Consider an ionic compound, MX, composed of generic metal M and generic, gaseous halogen X.
• The enthalpy of formation of MX is AH = -467 kJ/mol.
• The enthalpy of sublimation of Mis AH sub = 135 kJ/mol.
• The ionization energy of Mis IE = 411 kJ/mol.
• The electron affinity of X is AHEA = -339 kJ/mol. (Refer to the hint).
• The bond energy of X, is BE = 241 kJ/mol.
Determine the lattice energy of MX.
AHLattice =
457.5
kJ/mol

whats the meaning of /

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
