MCAT supercritical fluid - correct answer any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist the lowest frequency corresponds to the highest/lowest period? - correct answer highest (pay attention to the question, dumb mistake) constructive interference vs destructive interference - correct answer constructive makes it bigger, amplifies. Destructive goes against, flattens the wave. Review R/S Stereochemistry - correct ...

Lattice energy - - The enthalpy change when 1 mole of ionic compound is formed from its gaseous ions under standard conditions - It is the energy given out when ions of opposite charges comes together to form an ionic lattice Lattice energy is endothermic or exothermic? - - It is always exothermic because bonds are being formed (ionic bond) between oppositely charged ions, not broken Equation showing the formation of NaCl lattice - - Na^+(g) + Cl^-(g) > NaCl(s) The state of the opposite...
