The hawaiian islands are home to many endangered species. why do you think the hawaii department of agriculture is so strict about allowing nonnative species onto the islands?

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.)

The ammonia molecule in the diagram has the observed bond orientation because
