The theory of plate tectonics states that the outer layer of Earth is divided into large, rigid blocks called plates. What could happen that may lead to a change in this theory? Scientists discover new information about Earth's layers.
Scientists begin observing Earth's outer layer.
Scientists update their opinion of the theory.
Scientists revise the definition of theory so that it fits with what they believe.

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)
