The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

A pair of geologists with the U.S. Geological Survey, Denver, has created a model that shows Earth's subsurface may hold up to 5.6 × 10 6 million metric tons of natural hydrogen. In their study ...

Both ethanol and ether have the same molecular mass, however, their melting points and boiling points are different due to the ethanol containing hydrogen bonding. Ether is a symmetrical molecule ...

The hydrogen bonds that form water molecules are responsible for the many properties that make water a unique liquid. However ...

Now, a team of MIT researchers has taken a more detailed look at the specific chemistry that poses the risks of using hydrogen as a fuel if it leaks. The researchers developed a model that tracks ...
