No two water molecules forms bond with atoms on carbonic acid that are bonded to each other.(i)Suggest the type of interactions formed between carbonic acid and water molecules...[1] (ii)Draw the structure of a molecule of carbonic acid. Show clearly how the 3 water molecules are arranged...
Others are made by joining together two small hydrocarbon chains and removing a water molecule (two hydrogen atoms and one oxygen), making a bigger hydrocarbon chain in a process known as condensation polymerization. The more often you repeat this, the longer the polymer gets....
This is an attractive interaction between a hydrogen atom from a molecule or a molecular fragment X-H in which X is more electronegative than H, and an atom or a group of atoms in the same or a different molecule, in which...

24K Probe interesting facts about water, a vital resource for life on Earth. Discover the atoms that form a water molecule, how much of the Earth is covered with water, the difference between freshwater and saltwater, and other fun facts. Related...
when water becomes ice, the molecules bond together and they get sort of, uh, locked into place. They can't move around as much anymore. So each molecule is surrounded by other molecules, and they're all locked together. But what about the exterior of the ice? There's a layer of ...

hydrogenatomis attracted to a negativeoxygenatom on a nearbymolecule. Surfactants are chemicals that are able to reduce surface tension and spread on surfaces. Also, surfactants are believed to make water “wetter.” Gravity is a factor in water droplets. It allows the water to get into a cir...
What happens is that the chlorophyll behaves as a pump which removes electrons from a provider (the molecule of water), after the latter has been severed from the sunlight: Water photolysis (WP). Yet, to date, the performance of the WP has not yet been clarified. In a rather simplistic ...
The catalytic reaction first involves a glycosylation step resulting in covalent enzyme–substrate intermediate, which is subsequently hydrolyzed by a water molecule in a deglycosylation step, thereby restoring the enzyme-active site35,36. The glycosylation step has been shown to be rate-limiting for ...
