100
What are the 2 types of bonding
Ionic and covalent
100
what is kinetic and potential energy
Kinetic Energy: (KE)
Energy of motion or movement
Potential Energy: (PE)
Stored energy
100
What is Normal Boiling point
temperature at which vapor pressure equals atmospheric pressure
100
What is a hydrate
containing water
200
What groups are in the transition metals
groups 3-11
200
Name the properties of covalent bonding
Low melting and boiling points (due to weak attraction between molecules)
Do not conduct electricity due to lack of charged particles (ions)
200
draw and lable and exothermic curve
200
What is avagrados hypothesis
Equal volumes of gases at the same temperature and pressure have the same amount of particles
-particles include: subatomic particles
Example: H2 at 250K 1.25 atm, 2L
Cl2 at 250K 1.25 atm, 2L
200
what is an anhydrous
dry, when water is removed by heating
300
What is the name of group 1
Alkali metal
300
Name the properties of ionic bonding
-Hard
-Crystalline structure
-High melting/boiling point
-Soluble in water
-Conduct electricity only in aqueous/ liquid state
300
true or false: heating curve goes down
false!
300
What is atmospheric pressure
pressure of the atmosphere, & weight of the atmosphere around you
300
What is Grand Formula Mass (GFM)
Formula mass → amu (atomic mass units)
Gram Formula Mass → Gram / mol
**Add up all masses in a compound and round to the nearest tenth**
400
What is the name of group 17
halogens
400
What is HONC
H - hydrogen or halogen 1
O - oxygen 2
N - nitrogen 3
C - carbon 4
400
true or false: cooling curves go down
true!
400
What is vapor pressure
pressure exerted by a gas from the liquid
400
what is the mole calculations formula
number of moles = given Mass/ Grand Formula mass
500
What is the group of an Alkali Earth Metal
Group 2
500
What is MSNAP
Molecule Polarity
M - molecular
S - symmetrical (distribution of charge)
N - nonpolar
A - asymmetrical (distribution of charge)
P - polar
500
what is an element?
Substances that cannot be broken down
500
What are the Ideal gas laws
A gas is composed of particles in random, straight line motion
There is a transfer of energy between colliding particles
The volume of the individual gas molecules is negligible compared to the container they are in
Gas particles are considered to have no form of attraction
5. As temperature increases, velocity of a gas increases
500
what is the molarity formula
molarity= moles of solute/liter of solution
