We have discussed a three theories of bonding: Lewis Theory, Vespr, and Valence Bond Theory. Which of the following is a strength of Valence Bond Theory? A. This theory enables us to describe the formation of covalent bonds as a result of the overlap of hybrid orbitals. B. This theory enables us to predict the shape of covalent molecules. C. This theory enables us to make predictions about bond strength and bond length. D. This theory enables us to accurately predict the magnetic properties of molecules and ions.

If you want to create an electrical current, which situation would produce a solution capable of this

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
