Test 2 Stuff MaTTers Flashcards
If 2 atoms of identical electronegativity are bonded, what bond is it considered? The electrons are evenly shared between the atoms
The bond is nonpolar when 2 atoms of identical electronegativity are bonded
The greater the difference in electronegativity between atoms the more (BLANK) the bond
A bond is more polar when the bond has a greater difference in electronegativity.
The more electronegative atom “pulls” the shared electron toward itself. Sharing is not “equal”
The closer an atom is to (which element), the more electronegative it is?
The closer an atom is to fluorine
What is Fick’s Law?
Fick’s Law accounts for molecular weight, concentration gradient, solubility, and membrane interactions
Fick’s law states that diffusion across a semipermeable membrane is directly proportional to what two things?
Directly proportional to
Partial pressure gradient
Membrane solubility of gas
Fick’s law states that diffusion across a semipermeable membrane is inversely proportional to what two things?
Inversely proportional to
Membrane thickness
Molecular weight of gas
What is the definition of the boiling point of VAA?
It is the temperature at which the vapor pressure is equal to the ambient pressure
What is normal boiling point?
Normal boiling point is the temperature at which the vapor pressure of a liquid is equal to 1 atm of pressure
Vaporization occurs as the molecules escape from what state into what state of matter?
Vaporization occurs as the molecules escape from the liquid state into the gas state
As the temperature increases, the average (BLANK) energy of the molecules in the sample increase, eventually reaching the point where they are no longer constrained to remain in contact with the other molecules
As the temperature increases, the average KINETIC energy of the molecules in the sample increase
Boiling points decrease with decreasing pressure and increasing (BLANK)
Boiling points decrease with decreasing pressure and increasing ALTITUDE
What is specific heat?
Specific heat is the quantity of heat required to raise the temperature of 1 Gm (1mL) of a specific substance by 1C
