The molar entropy of argon {Ar) is given by S0 = {36.4 + 20.8 ln T) J K-1 mol-1 Calculate the change in Gibbs energy when 1.0 mole of Ar is heated at constant pressure from 20°C to 60°C. (Hint: Use the relation Jlnxdx = xlnx - x.)

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.

first one is the correct answer

tracks, burrows, eggshells, nests, tooth marks, or gastroliths
