LESSON 5 QUIZQuestion 1 of 254.0/ 4.0 PointsEach of the three resonance structures of NO3–has how many lone pairs of electrons?A.8B. 10C. 13D. 7E. 9
Feedback: See Chapter 8Question 2 of 254.0/ 4.0 PointsWhen comparing Be2and H2:I.Be2is more stable because it contains both bonding and antibonding valence electrons.II.H2has a higher bond order than Be2.III.H2is more stable because it only contains 1s electrons.IV.H2is more stable because it is diamagnetic, whereas Be2is paramagnetic.
Feedback: See Chapter 8Question 3 of 254.0/ 4.0 PointsNitrous oxide (N2O) is sometimes called “laughing gas”. What is the formal charge on the centralnitrogen atom in the most favorable Lewis structure for nitrous oxide based on minimizing formal charge overall?
