Which of the following characteristics can be written only in space C? O Formed between positively and negatively charged ions
O Occurs due to the sharing of electrons between two non-metal atoms
0 Occurs in substances that are mostly solids at normal temperature and pressure
O Formed between an atom with very high electronegativity and an atom with very low electronegativity

Iam in desperate need of with this !

Newtons second law deals most cosely with

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.
