A beaker containing a chemical reaction feels hot to the touch. According to the law of conservation of energy, what best predicts the stability of the products?
1. If the reactants absorbed thermal energy when they reacted, the products must have more energy. The products will be more stable.
2. If the reactants absorbed thermal energy when they reacted, the products must have more energy. The products will be less stable.
3. If the reactants absorbed thermal energy when they reacted, the products must have more energy. The products will be less stable.
4. If the reactants released thermal energy when they reacted, they must have lost an equal amount of potential energy. The products will be less stable.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
