Term
Polar bond
Definition
electrons being shared unequally
Term
nonpolar bond
Definition
electrons being shared equally
Term
ion
Definition
an atom that has gained or lost electrons to end up with full suborbitals
Term
dipole
Definition
a molecule with a slightly negative and slightly positive end
Term
dipole-dipole attraction
Definition
when two dipoles are attrected to each other
Term
ion-dipole attraction
Definition
an ion attracted to the oppositly charged end of a dipole molecule
Term
hydrogen bond
Definition
when two molecules that have a O,N,or F bonded to an H come close together the O,N,or F (that are bonded to an H) becomes attracted to the positive H
Term
ion-induced Dipole attraction
Definition
nonpolar molecule in the presence of an ion, its electrons are influenced by the charge of the ion. Negative charge reples the electrons causing one side of the molecule to become slightly positive and the other side slightly negative
Term
dipole-induced dipole attraction
Definition
the presence of a dipole near a nonpolar molecule can induce a slightly negative or positive charge in the close nonpolar molecule.
Term
induced Dipole-induced dipole
Definition
when electrons being shared in bonds happen to reside in one pole or end of the molecule causing it to be slightly negative and leaving the other end temporarily without electrons causing it to be slightly positive
Term
name the four rule of significant figures
Definition
  1. All non-zero numbers(1-9) are always significant
  2. All zeros between Non-zero numbers are always significant
  3. Allzeros which ar simultaneously to the right of the decimal pointand at the end of the number are always signficant
  4. All zeroes which are to the left of a written decimal point and are in a number >=10 are always significant
Term
name the equation you use to solve for heat
Definition
Q=m*c*deltaT
Term

define the variable of

Q=M*C*deltaT 

Definition

Q= heat

M= mass

C= constant

DeltaT= change in temp

 

Term
what is the unit of heat
Definition
Joules(J)
Term
what is electronegativity
Definition
the ability to attract electrons
Term
what type of intermolecular attractions do nonpolar molecules typically form?
Definition
induced dipole-induced dipole
Term
why is soap so cool
Definition
because it has an ionic part and a nonpolar part
Term
to get oil off of a piece of wood you should use
Definition
paint thinner or soap
Term
what is the correct name for FeCl3
Definition
Iron(III) Chloride
Term
what is the name for Ca(NO3)2
Definition
Calcium Nitrate
Term
what is the chemical formula for scandium oxide
Definition
Sc2O3
Term
what is the chemical formula for chromium(VI) Oxide
Definition
CrO3
Term
how does soap break down oil to get it off of something
Definition
the ionic and nonpolar parts attach to the polar parts of an oil molecule and break it down
Term
ionization energy
Definition
the energy required to remove an electron from their outer most electron orbital
Term
oxidation state
Definition
the charge you end up with after an element looses or gains electrons
