For this question, consider only the coulomb energy component (the largest) between two atoms. given that nacl (formed from na+ and cl–) has melting temperature of 1074 k (or 801 c), see table 2.3, roughly estimate the melting temperature in kelvin of mgo from that of nacl, i. e., the ratio of coulomb energy. (assume that the equilibrium bond lengths are given by the sum of ionic radii, see table inside front cover of textbook.)

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
