A student made the Lewis dot diagram of a compound as shown. What is the error in the Lewis dot diagram?
A. The Ca atom should transfer only one electron to Ci because the formula is CaCi.

B. The number of dots around Ca should be one because Ca has to transfer only one electron to CI.

C. The Ca atom should transfer only one electron to CI, and the second electron should be transferred to another CI atom.

D. The CI atom should transfer two electrons to Ca because it has more electrons than Ca, so formula becomes CaCI*2

12. complete each of the following word equations for synthesis reactions. a. sodium + oxygen -> b. magnesium + fluorine -> 13. complete and balance the equations for the decomposition reactions. a. hgo -> [with the triangle heat symbol above the arrow] b. h2o(l) -> [with "electricity" written above the arrow]

Write a paragraph that provides examples of each stage of volcanic activity, a description of the volcano, and facts about each stage.

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
