In stoichiometry, molar mass is used to:

relate the mass of a substance to the amount in moles of that substance

In stoichiometry, mole ratio is used to:

convert the amount in moles of one substance to an amount in moles of another substance

Molar masses are determined from:

the periodic table

The type of stoichiometry problem that involves the most steps is a:

mass-to-mass conversion

If, in the reaction A + B->C + D, the quantity of B is insufficient to react with all of A,

B is the limiting reactant.

measured amount of product obtained from a chemical reaction is the

actual yield

hypothetical gas that perfectly fits all the assumptions of the kinetic-molecular theory is known as:

an ideal gas

Assumption of the kinetic-molecular theory of gases

temperature of a gas depends on the average kinetic energy of the gas particles

used to calculate the kinetic energy, KE, of a moving particle

KE= ½mv²

physical properties of gases

absence of definite volume, high compressibility, fluidity

states of matter that are fluid

gases and liquids

liquid can be described as a form of matter that:

has a definite volume

liquids are more ordered than gases because liquids have:

stronger intermolecular forces and lower mobility of the particles

Examples of intermolecular forces (IMAFs):

hydrogen bonding, London Dispersion forces, dipole-dipole interactions

water forms roughly spherical drops because of its:

surface tension

If energy as heat is removed, most liquids will eventually


According to the kinetic molecular theory, particles in solids

vibrate around fixed points

order of strength of intermolecular forces from least to greatest

liquid, solid, gas

Equilibrium is characterized by

opposing processes occurring at equal rates

process of changing from a solid to a gas is known as


Temperature at which the vapor pressure of a substance equals atmospheric pressure is its

boiling point

amount of energy needed to melt one mole of a substance is its molar

enthalpy of fusion

Bond between oxygen and hydrogen in a water molecule is


Reason for the relatively low density of ice:

empty spaces between molecules

water's relatively high boiling point is the result of

hydrogen bonding

Heterogeneous mixture that has large particles that settle out is called a


Exhibits the Tyndall effect


When the size of the particles in a solution and in a colloid are compared, the particle size in the solution is


A substance that is not soluble in a polar solvent is most likely


Increases the speed of the dissolving process of a solid in a liquid:

increasing temperature of the solvent, increasing surface area of the solute, shaking or stirring the solution

solution that contains the max amount of dissolved solute at a particular temperature is said to be


What happens when an acetic acid, a weak electrolyte, dissolves in water?

hydronium ions form, resulting solution will conduct electricity, most of the acid remains as nonionzed molecules in equilibrium with ions

process of forming a solid by combining two ionic solutions is called


When a nonvolatile solute dissolves in a solvent, the vapor pressure of the solvent:


When a nonvolatile solute dissolves in a solvent, its freezing point______the freezing point of a pure solvent.

is less than

When a nonvolatile solute is added to a solvent, its boiling point_____the boiling point of a pure solvent

is greater than

particles in a liquid are usually

closer together and lower in energy than those in a gas

In general, most substances are

most dense in the solid state

solids and liquids both have this property

definite volume

molecules at the surface of a liquid can enter the vapor phase only if

their energy is high enough to overcome the attractive forces in the liquid

at pressures greater than 1 atm, water will boil at

Ions are formed from solute molecules by the action of the solvent in a process called


colligative properties depend on

the concentration of the solute particles

which elements exist as diatomic molecules?

Br I N Cl H O F

one part of the molecule has a slight positive charge and the other a slight negative charge (one is more electronegative)

Polar Molecules i.e. H₂O

molecule that shares electrons equally and does not have oppositely charged ends

Nonpolar Molecules i.e. H₂, O₂

compounds where two or more ions are held next to each other by electrical attraction (M+NM; cation+anion)

Ionic Compounds i.e. Fe₂(SO₄)₃

type of attractive intermolecular force that exists between two partial electric charges of opposite polarity

Hydrogen Bonding

attractive forces between the positive end of one polar molecule and the negative end of another polar molecule


the weakest intermolecular force; a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.
