Which best describes how charges are distributed on a water molecule?
Water is highly cohesive
. Its molecules tend to resist increases in their motion. When water is heated, some of the energy is used to disturb the hydrogen bonds between neighboring molecules.
How is charge distributed in a molecule of water?
In a water molecule, the oxygen atom and hydrogen atoms share electrons in covalent bonds, but the sharing is not equal. … The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and
a slight positive charge near its hydrogen atoms
.
Which best describes how the partial charges are distributed on a water molecule?
Which best describes how charges are distributed on a water molecule? 1) The oxygen end is positive relative to the end with the two hydrogen atoms. 2) The oxygen end is negative relative to the end with the two hydrogen atoms. 3)
The charge is neutral and equal throughout the molecule.
Are the charges on a water molecule are distributed equally?
The charges on a water molecule are distributed
equally
. … The property of water called cohesion causes water molecules to repel each other. False. negatively charged ions are called anions.
Which of the following is the best description of a water molecule?
In fact, water is best described as
a polar molecule
. Polar molecules are molecules that don’t share their electrons very well. If you look at our drawing of water, you’ll see that oxygen and its hydrogens are bonded together.
What are the two charges present in a water molecule?
The covalent bonds are therefore polar, and the oxygen atoms have a slight negative charge (from the presence extra electron share), while the
hydrogens
are slightly positive (from the extra un-neutralized protons). Opposite charges attract one another.
Is water a universal solvent?
Water is called
the “universal solvent”
because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. … This allows the water molecule to become attracted to many other different types of molecules.
What does it mean when we say water is adhesive?
Adhesion refers to the
tendency of water molecules to be attracted to other substances
.
What part of water is positive?
The oxygen is the negative end of the molecule, while
the area between the hydrogen atoms
is the positive end of the molecule.
Which best describes how charges are distributed on a water molecule quizlet?
Which best describes how charges are distributed on a water molecule?
The oxygen end is negative relative to the end with the two hydrogen atoms
. … Its molecules tend to resist increases in their motion. When water is heated, some of the energy is used to disturb they hydrogen bonds between neighboring molecules.
Is water a good solvent?
Water is capable of dissolving a variety of different substances, which is why it is
such a good solvent
. And, water is called the “universal solvent” because it dissolves more substances than any other liquid. … This allows the water molecule to become attracted to many other different types of molecules.
How much positive and negative charge is there in a water molecule?
Therefore, a water molecule has an equal amount of positive and negative charge which is
1.33×107C
. Note:Water is formed by the sharing of electrons between two hydrogen atoms and one oxygen atom through the formation of a covalent bond.
Why do water molecules have high cohesion?
Water is highly cohesive—it is the highest of the non-metallic liquids. … More precisely, the positive and negative charges of the hydrogen and oxygen atoms that
make up water molecules makes them attracted to each other
.
Is water an element or compound?
water, a substance composed of the
chemical elements hydrogen and oxygen
and existing in gaseous, liquid, and solid states. It is one of the most plentiful and essential of compounds.
Which best describes the bonding in a water molecule?
Explanation: A bond formed by sharing of electrons is known as a covalent bond. Therefore, an oxygen atom combines with two hydrogen atoms by sharing of electrons. Thus, we can conclude that the statement
an oxygen atom shares an electron pair with each H atom
, best describes the bonding in a water molecule.
Why is water called water?
The word water
comes from Old English wæter
, from Proto-Germanic *watar (source also of Old Saxon watar, Old Frisian wetir, Dutch water, Old High German wazzar, German Wasser, vatn, Gothic (wato), from Proto-Indo-European *wod-or, suffixed form of root *wed- (“water”; “wet”).
