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.)

What is the indicator of the number of ions in solution? the amount of conductivity the amount of precipitate the amount of solute added

How is the way a mixture is combined different from how a compound is combined?
