Which statement is false? Group of answer choices Electrons occupy MOs by following the Aufbau Principle. In MO theory all electrons are accounted for, not just the valence electrons. Electrons occupy MOs by following Hund’s Rule. No two molecular orbitals for any molecule ever have the same energy. Electrons occupy MOs by following the Pauli Exclusion Principle.

Which of the following signs of a chemical reaction are observed in the reaction of potassium with water? precipitate formed temperature change smell produced gas produced color change

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
