Answer:
exothermic, with a decrease in entropy
Explanation:
Whenever you produce heat as a product in a reaction, the reaction is exothermic. To determine entropy, we know we have 4 moles of gas on reactant (1 from N2 and 3 from H2) and in produce side we only have two moles (2 from NH3) thus since we are decreasing the number of gas molecules, there is going to be less disorder, hence decrease in entropy.

Answer: they are held together by hydrogen bonds I believe
Explanation:
<span>Echinoderms
contain internal skeletons similar to the kind that vertebrates have. This
internal skeleton is made up of calcium carbonate. They are marine animals.
Some species of the echinoderm phylum include starfish, sea cucumbers and sea
urchins.</span>
