...Water (, HOH) is the most abundant molecule on Earth's surface, constituting about 70% of the planet's surface. In nature it exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. At room temperature, it is a nearly colorless with a hint of blue, tasteless, and odorless liquid. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some of its properties may vary slightly from those of the pure substance. However, there are many compounds that are essentially, if not completely, insoluble in water. Water is the only common substance found naturally in all three common states of matter—for other substances, see chemical properties. Water is essential for life on Earth. United Nations Water usually makes up 55% to 78% of the human body. Re: What percentage of the human body is composed of water? Jeffrey Utz, M.D., The MadSci Network Read full entry

How do different charges If I put a negative charge to
water, what exactly will
happen to the water molecule?
Since a negative charge is
defined as an excess of
electrons, does this mean the
water molecule will accept
more electrons?
Will the electrons be accepted
into the hydrogen's atom
(since it has room for 2
electrons)?
What about a positive charge,
will it extract (ionize)
electrons from the water
molecule, and if so will the
water molecule still remain a
water molecule after it is
ionized?

well H20 when it gains a hydrogen molecule becomes hydronium H30+ and when it loses a hydrogen molecule it becomes hydroxide OH- and an electrical current going through the water can separate the hydrogen and oxygens so gaining and losing charges in water is basically when it gains or loses an H |

What is the structure of a The question says, Describe
the structure of both a water
molecule and the compound
water. I looked up a site and
it said all compounds are
molecules but not all
molecules are compounds. I
really don't understand this.
Please help!

A compound is a combination of two or more elements. NaCl is a compound, not a molecule, because it dissociates into Na+ ion and Cl- ion. A molecule involves covalent bonds. Glucose is a molecule. To describe water as a compound, I would say it is H2O, or hydrogen oxide. To describe water as a molecule, I would say it is H-O-H. |

What happens to a water Take a water molecule, and
remove a hydrogen atom, what
is left?
This is not for school simply
a curiosity,
