Calculate the change in entropy if br2(l) is converted into gaseous br atoms. 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)

Which element would mostly likely have an electron affinity measuring closest to zero

Is 9 correct? and can someone me with 10? it’s due tomorrow, you
