Can someone inidicate for me the carboxylic acid, the alcohol and the amide in pantothenic acid? Thnx in advance.

Some animals that try to adapt to climate changes eventually die due to starvation, as climate change alters the web.

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.)

How much heat is added if 0.814g of water increase in temperature by 0.351 degree c?
