What is the Lewis structure of methane? Are hydrogen bonds polar or nonpolar? Why is water a polar compound? What type of bond forms between water molecules? What's the difference between a dipole and a polar molecule? Which one of the following gases would dev...
The good permeability of CO2 through the Pure Matrimid and all of the three MMMs may be attributed to the smaller kinetic diameter of CO2, its polar nature, and creation of significant interactions between the CO2 molecules and the polar groups present in the Matrimid structure. These are the ...

Draw the Lewis structure for SO2. Show all lone pairs and locate any formal charges. Determine the number of valence electrons, give the overall shape of the molecule, and indicate whether the molecule is polar or nonpol...
