You have measured the water and weighed the plaster correctly for a maxillary impression and base. A few seconds after you begin mixing, you note that the mix is very dry. You know
you measured correctly.

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 atom or ion is the largest? a. k b. k+ c. ca d. ca2+ e. li

An electron moved from shell n = 2 to shell n = 1. what most likely happened during the transition? a fraction of a photon was added. a photon of energy was absorbed. a fraction of a photon was removed. a photon of energy was released.
