Water
What how does water arrange around ions?
...
What is the difference between the covalent bonds in water and in oxygen?
The bonds in water are polar and the bonds in oxygen are nonpolar.
acid
increase of hydrogen ions and decrease of hydroxide ions
water
polar molecule
hydrogen bond ex
pull between a partially positive hydrogen atom on one molecule and a partially negative oxygen atom.
solvent
the agent which is dissolving the solute
specific heat
the temperature to measure the molecule motion
how much difference is there in an ion concentration between each values on the pH scale?
10x
What is the temperature at which water reaches maximum density?
4 degrees celcius
What is a polar molecule?
A molecule with opposite charges at opposite ends Correct
buffer
A solution to which the pH is resistant to small additions of acids or bases. Buffers can bind up or release H+ in order to keep the ph pH constant.
Cohesion occurs due to which type of bonding?
Hydrogen
Water is composed of what two elements?
Oxygen and hydrogen
What is the nature of bonds between carbon and hydrogen?
The bonds between carbon and hydrogen are nonpolar covalent bonds. Neither carbon-to-carbon nor carbon-to-hydrogen bonds are polar.
Covalent bond
The elements of a water molecule are held together by which type of bond?
Covalent bonds are formed by....
The sharing of electrons.
Why do the atoms of a water molecule have partial charges?
There is an unequal sharing of electrons between the atoms Correct
capillary action
a combination of the adhesive and cohesion properties of water that allow it to move from the roots to the leaves in plants.
solute
a dissolved subtance
solution
a homogenous mixture of two or more substances
aqueous solution
a solution in which WATER is the solvent
cohesion
a substances capacity to resist being broken when it is stretched or placed under tension
Water stuck to the windshield is an example of what?
adhesion
Water falling from clouds forms a rain drop because of what?
cohesion
base
decrease of hydrogen ions and increase of hydrogen ions
Hydrogen Bonds
form between the hydrogen and oxygen atoms of different water molecules. one is negative and one is positive
Which of the following is not one of water's special properties?
high visocity
polarity
the hydrogen atoms of the water molecule have a slight POSITIVE charge while the oxygen atom has a slight negative charge.
adhesion
the intermolecular attraction between unlike molecules like OIL and WATER
freezing point
the temperature at which a liquid changes to a solid
