Water is 1g/cal/degree C
|
|
|
Lattice structure
|
when water is at a solid state the hydrogen bonds release energy and become stabilized into a lattice structure
|
|
|
What charge does the nucleus have?
|
Positive charge
|
|
|
Difference between covalent and ionic bonds

|
|
|
Ph Levels
|
0-7 acidic- lots of hydrogen atoms to donate
8-14 basic- able to accept H+ easily |
|
|
The Universal Solvent
|
H2O
|
|
|
Polar solvents dissolve in water means..
|
like dissolves like
|
|
|
why is ice less dense?
|
the lattice structure has a lot of space between each molecular bond
|
|
|
cohesion
|
attraction between water molecules and cells in stems of plants that causes water to move against gravity if needed!
|
|
|
cohesion in plants is called
|
evapotranspiration/ transporation
|
|
|
Difference in strong and weak acids
|
strong acids like to donate H+ and weak acids are more reluctant to donate.
|
|
|
Adding water to a weak acid will cause...
|
a weak base

Between water molecules are
|
hydrogen bonds
