Groups of college students pursue the study of chemical compounds with similar reactivity. if they wish to do an in-depth background study on periodic trends, they should most likely a) consult only their chemistry professors. eliminate b) rely exclusively on each other’s background knowledge. c) consult chemistry professors, chemistry textbooks, and scientific journals. d) consult chemistry professors and further study through scientific-fiction movies.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.
