Quiz: Partial Charge
Ans: -On polar covalent bonds
-Electrons are shared unequally
Quiz: Molecule shape affects polarity b/c
Ans: -it affects the type of bonds formed.
-If central atom shares electrons, it is nonpolar.
-If central atom takes electrons, it is polar
Quiz: Hydrogen Bonds
Ans: -Weak interaction between 2 molecules or different types of the same
molecule
-Results from the attraction between a hydrogen atom with a partial charge
and another with a partial negative charge(FON)

,Quiz: C, H, N, O, P, S
Ans: Make up 99% of the atoms in your body
Quiz: Covalent bonds
Ans: Sharing of unpaired electrons (form molecules)
Quiz: Polar Covalent
Ans: -Electrons not shared equally between atoms
-pulled to more electronegative element
-causes a partial charge on the atoms
Quiz: Ionic bonds
Ans: -electron is completely transferred
-cation(+): lose electron
-anion(-): gains electron
-atoms have full charge
Quiz: nonpolar covalent
Ans: electrons shared equally between atoms. Atoms have no charge.
Quiz: Solvent
Examstudy - Stuvia US
, Ans: liquid in a solution
Quiz: Solutes
Ans: Substances dissolved in solvent in a solution
Quiz: Water
Ans: - Water is a good solvent b/c polarity and ability to form hydrogen
bonds
-Hydrogen bonds allow for cohesion and surface tension

-Energy: ability to acquire and use energy
-Evolution
Quiz: Louis Pasteur's experiment
Ans: -put nutrient broth in flasks, boiled it to kill all existing cells and waited
to see if cells could be created.
-Concluded: All cells come from preexisting cells
