Do you ever wonder why scientists spend time looking for water on other planets? That means that while the atoms are "sharing" the electrons, the oxygen hogs them a bit closer, creating a partial negative charge on that side of the molecule, and a partial positive charge on the Hydrogen side, To say that oxygen is electronegative fails to grasp the whole picture here. Adhesives are designed for specific applications. More bonds are broken than are formed. Whats Coherence in Writing?

They play a role in many water-based processes in biology, including the movement of water to the tops of trees and the drainage of tears from tear ducts in the corners of your eyes. It is because water is essential to life; even minute traces of it on another planet can indicate that life could or did exist on that planet. Oil and water do not mix. (credit: Cory Zanker). This means that ice floats on the surface of a body of water (Figure 3b). This is referred to as a sphere of hydration and serves to keep the particles separated or dispersed in the water. 2, 3 On the other hand, one of the major problems related to these materials is the prediction of their life span, and thus their reliability. The first thing that comes to mind when talking about adhesion is naturally gluing. Water consists of molecules with the composition H2O (two small atoms of hydrogen and one larger atom of oxygen). Waterproofing components for roofs serve as a shield between the structure and precipitation and snow, preventing potential leakage.
