As water freezes, its molecules spread apart into a specific arrangement that makes frozen water less dense than liquid water. Bases do not react with metals in the way that acids do. As shape is critical for biochemical processes, this is also one of water's most important roles. The bond is too strong for cohesion to break it. This causes surface tension and allows some organisms to walk on the surface of the water. What are the properties of water quizlet? What charge does the hydrogen have in a molecule of water?
