Why do you think lone pairs of electrons create greater repulsion when located near other lone pairs or bonding pairs? Orbitals containing lone pairs of electrons require more space

than orbitals containing bonding pairs. Why do you think this is the case? What does the

presence of one or more lone pairs of electrons do to the bond angles in a molecule (in other

words, do bond angles get larger, smaller, or remain unchanged?)

Acontrol during an experiment. might change remains constant does not exist does change

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)

Which of these is an example of pseudoscience? a) predicting the time of sunrise based on data on position of earth b) predicting the date of the moon phases based on data on position of earth c) predicting eclipses based on the position of the sun and the moon d) predicting future events in a person's life based on the position of the moon
