... fig 5. The Lewis structure of HOH. How many lone pair(s) of electrons are on the central atom, O? Adapt the molecular model of NH3 to get a model of HOH. How would you describe the shape of a water molecule? No fancy name required. Use the bond angles in CH4 and NH3 to predict the H–O–H bond angle i ...

... Plasticizers (usually diesters) are chemicals that separate chains to make them softer and more flexible. eg. Plasticizers are added to PVC which by itself is hard and brittle due to the strong permanent dipoles of the Cl groups. Plasticers can evaporate out, resulting in plastics becoming more brit ...

Adhesion
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are certain emergent mechanical effects that will also be discussed at the end of the article.
