Four models of chemical bonding are illustrated in the diagram. Th e red spheres represent the nuclei and core electrons of atoms and blue areas represent where valence electrons are located. Model 1 Model 2 Model 3 Model 4 Which statement below correctly identifi es the type of bonding for the compound listed? (A) MgCl2(s) bonds according to Model 1 because valence electrons are shared between the atoms. (B) CO2(g) bonds according to Model 1 because valence electrons are shared between the atoms. (C) Li(s) atoms are bonded according to Model 4 because valence electrons are free to move about the substance. (D) N2(g) bonds according to Model 4 because valence electrons are shared throughout the entire substance.
Chem 130 Lecture Notes 1.19.16 and 1.21.16 Ex. Tennis balls are usually filled with air or N gas to a pressure above atmospher2c pressure to increase their "bounce". If a particular tennis ball has a volume of 144cm and contains 3 0.33g of N gas, 2hat is the pressure inside the ball at 24°C Given: V=144 cm = 144 mL 3 PV=nRT
