Hi :) how to do 4(b)?

Who is better, messi or cristiano, i need this for a chemistry class. asap

Calculate the change in entropy if br2(l) is converted to br2(g). s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)

When the water vapor cools it condenses select a number that represents his process on the
