Is ST_GeomFromText better than providing direct geometry?

CHEMISTRY PLEASE HELP IM DESPERATE in 5 hours thx?

• usually i dont ask homework questions, but i left my textbook at home and its due tomorrow. PLEASE HELP ME. 1. A resonance structure is one of two or more Lewis structures for a single molecule, unable to be represented by a single Lewis structure. True/False 2. Barium is an exception to the octet rule and will hold a maximum of four electrons in its valence shell. True/False 3.Hydrogen is an exception to the octet rule. This is because: A. Hydrogen can have more than eight electrons in its valence energy level. B.Hydrogen possesses only the s-sublevel providing it with enough room for only two electrons. C.Hydrogen is a nonmetal and does not need to have more than one electron in the valence energy level. D.None of the above 4.The molecule BH3 is arranged in a trigonal planar molecular geometry. True/False 5.The molecule SCl6 is arranged in a trigonal bipyramidal molecular geometry. True/False i feel so weird asking for homework help but im really desperate , thanks

• Answer:

  1. true 2. false, it's boron not barium 3. B 4. true 5. false, it's octahedral
