The change in entropy, Srxn , is related to the the change in the number of moles of gas molecules, ngas . Determine the change in the moles of gas for each of the reactions and decide if the entropy increases, decreases, or has little or no change. A. 2H2(g)+O2(g) 2H2O(l) ngas= mol The entropy, Srxn , increases. decreases. has little or no change. how did japan change during the Heian empire/period What I want you to do is think of yourself as a tourist who just landed in Nebraska.
