    1. Ammonia salt/ Barium Hydroxide demo Did this reaction occur spontaneously? Is the reaction exothermic or endothermic? NH4Cl + Ba(OH)2 .8H2O ? BaCl2 + 2NH3 + 10H2O

    2. Entropy: Disorder/ Chaos Entropy increasing is a spontaneous process Molecules tend to move spontaneously to a state of maximum randomness 2nd law of Thermodynamics: Entropy of universe is increasing Symbol DS Sign convention DS+ when randomness increases Sign convention DS- when randomness decreases

    3. Which of the following are spontaneous processes? A) Heat flow from a cold object to a hot object B) Diffusion of perfume molecules from one side of the room to the other C) Decomposition of rust (Fe2O3.H2O) to iron metal, oxygen, and water D) Burning wood E) A ball rolling down a hill
