properties of water
mixtures
100
sharing of electrons
What is a covalent bond
100
contains a proton, electron, and a neutron
What is an atom
100
universal solvent
What is water
100
Allows water to resist external forces because of the cohesive forces of water
What is surface tention
100
A substance composed of 2 or more elements that are physically combined but not chemically combined
What is a mixture
200
a weak attraction between a positive polar H atom and another polar negative atom
What is a hydrogen bond
200
positively charged and contained in the nucleus of an atom
What is a proton
200
pH of 7
What is neutral
200
water molecules are attracted to molecules of another substance
What is adhesion
200
A homogeneous mixture of 2 or more components
What is a solution
300
an uneven distribution of electrical charge
What is polarity
300
electrons involved in bonding
What are valence electrons
300
prevents sudden changes in pH
What is a buffer
300
Water molecules in contact with a different surface will "climb" that surface because of cohesive and adhesive forces until gravity stops the process
What is capillary action
300
The substance that dissolves in a solvent
What is a solute
400
forms between 2 nonmetals
What is a covelent bond
400
smallest particle o matter that makes up all living and nonliving things
What is an aom
400
pH greater than 7
What is a base
400
water molecules are attracted to other water molecules
What is cohesion
400
Components can be evenly distributed by shaking, but the components will eventually settle out
What is a suspension
500
an electrostatic attraction between ions
What is an ionic bond
500
mass of the proton and neutron combined
What is the atomic number
500
tells us the concentration of hydrogen ions in a solution
What is the pH scale
500
Amount of heat it takes to raise the temperature of water by 1 degree
What is heat capacity
500
