water
pH
mishmash
100
parts of an atom and their charges
What is proton + neutron- neutral electron-
100
This bond shares valence electrons equally
What is nonpolar covalent
100
The type of bond in a water molecule
What is polar covalent
100
pH below 7
What is an acid
100
The 4 most common elements in the body
What is carbon, hydrogen, oxygen and nitrogen
200
the atomic mass of an atom with 5 protons and 5 neutrons
What is 10
200
Ions and their charges
What is cation + anion -
200
water molecules sticking to themselves
What is cohesion
200
pH of a solution with H+ concentration of 10-8 M
What is 8
200
This bond only occurs in very close proximity with "Hot Spots"
What is Van der Waals interactions
300
These can break chemical bonds and cause molecular damage
What are radioactive isotopes
300
The bond that shares valence electrons unevenly
What is polar covalent
300
Water's surface tension and heat storage capacity are accounted for by this interaction between molecules
What is hydrogen bonding
300
A pH of 4 is this many times more acidic than a pH of 7
What is 1,000
300
definition of kilocalorie
What is amount of heat required to raise the temperature of 1 kg of water 1 C
400
These are needed in very small quantities in the body
What is trace element
400
This bond is stable in a dry environment, but dissociates in water
What is ionic
400
Which contains more heat, but has a lower temperature a boiling pot of water or the ocena
What is ocean
400
These help shift pH by releasing or accepting H+ to keep a solution in range
What is buffer
400
What happens to the kinetic energy of a drink when ice is added to it and it melts
What is decreases
500
Atomic #
What is # of protons
500
This is a weak bond that is associated with polar covalent bonds
What is hydrogen bond
500
List and explain 4 properties of water
What is 1- cohesion/adhesion/surface temperature 2-moderates temperatures 3- less dense when it freezes (floats) 4- solvent of life
500
Emissions of these 2 substances cause acid precipitation
What is nitrogen oxides and sulfur dioxide
500
Water moving from roots to leaves includes these 3 properties of water
What is cohesion, adhesion, capillary action
