Suppose the wind speed in a hurricane is [09] mph (mi/h). (a) Find the difference in air pressure (Pa) outside a home and inside a home (where the wind speed is zero). The density of air is 1.29 kg/m3. (b) If a window is 61 cm wide and 108 cm high, find the net force (lb) on the window due to the pressure difference inside and outside the home.
Describe the bonding in SeO2 in valence bond terms. Note whether or not there is delocalized bonding and explain how molecular orbital theory can be useful here.
