  1. On Test to Review: Equations: E = w + q Hess’s Law q = c x m x ΔT q= ΔH x n ΔG = ΔH -T ΔS ΔT = Tinitial – Tfinal Vocab: work system entropy heat universe energy specific heat capacity temperature Free energy enthalpy Joules energy Calories Calorimeter exo/ endothermic enthalpy of fusion/ cond/ vap/ solid/ combustion Be able to use these equations, and also combined with Stoichiometry problem solving (If this reaction produces ΔH = -524 kJ/ mol, how much energy is released when 24g of CH4 is burned?) When are reaction exothermic or endothermic, organizing or chaotic, spontaneous or non-spontaneous?
