Remember when your elementary school teacher explained that a water molecule has two Hydrogen atoms and one Oxygen atom that are bonded together to form H2O?What your teacher may not have told you is that there are four types of hydrogen in the world. In fact, there’s ONLY ONE type of ...
Today I’m going to explore something more fundamental, how does O2 get into the water in the first place? We know how oxygen gets into the water. We all know that water is H2O, which means it is two parts hydrogen and one part oxygen. Oxygen gets into the water in 3 ways.“It ...

How do plants acquire carbon, hydrogen, and oxygen?
Most hydrogen and oxygen atoms in water are stable but traces of both elements are also present as heavier isotopes (同位素) . The heaviest raid(列阵)falls first. As a result storms that form over the Pacific deliver heavier water to California than to Utah. Similar patterns exist throughout...
How many liters of oxygen are required to react completely with 2.4 liters of hydrogen to form water? H2 + O2 rightarrow H2O. How many moles of oxygen are needed to react with 4.6 moles of hydrogen in the following reaction? 2H...
Hydrogen bonds are naturally seen in the water. In water molecules, two hydrogen atoms are covalently bonded to an oxygen atom. Here these hydrogen atoms can form hydrogen bonds with oxygen atoms of other water molecules. This lets water molecules align in such a way that the oxygen a...
