The molar mass of water is equivalent to the mass of one mole of water molecules. One mole is a scientific form of measurement in chemistry. Elements need to have equal amounts of protons and electrons to be stable, but they can vary in the amount of neutrons they contain. The amount o...
In a process known as osmosis, molecules seem to move the opposite way across gradients, from low to high concentrations of particles. This can be seen in cases when ablocks particles from passing through because they are too large. The water molecules in the solution may be small enough to...
Heliumis the second element on the periodic table and the second most abundant element in the universe. On Earth, it's normally a transparent gas. It can be cooled into a transparent liquid, sort of resembling water, except much, much colder. It ionizes into a reddish orange glowing gas....
The next picture is of the egg I soaked in water. Though you may not be able to tell from the picture, the egg is more round and swollen than it was before it was in the water. As a side note, this egg was also a little more firm than the rest. The next picture is of the ...
water requires one of several conditions to be in place. For a body of water such as a lake, river, or ocean to allow some of its water molecules to switch from a liquid and be released as a water vapor into the air, heat from the sun must be present to initiate the process. A ...
The technique has been used to reveal the difference in bond polarity between two structurally identical but chemically distinct molecules. Jascha Repp of the University of Regensberg in Germany and colleagues were keen to improve images taken in a variation of AFM – dubbed kelvin probe force ...

A critical test of the generalised Stokes-Einstein relation, mapping the friction of single molecules to the viscoelastic response of the macroscopic sample, disproves the relation for Newtonian fluids, but substantiates it exemplarily for water and a moderately supercooled liquid. The employed approach...
1 sugar molecule is processed with 2 ADP and 2 free phosphates into 2 molecules lactic acid with 2 ATP and 2 water molecules (+2 protons). C6H12O6 + 2 ADP + 2 Pi = 2C3H603 + 2ATP + 2H20 Step 34: Preservation of Sourdough When you go on a holiday and don't find a babysitter ...
The first really amazing form of carbon to be discovered is called buckminsterfullerene, after Buckmister Fuller the inventor and popularizer of many geodesic dome structures. Buckmisterfullerene is often referred to as "bucky balls" because it consists of molecules of 60 atoms in a graphite-like...
