Chemistry Final Exam Review
1.0 x 10 -14 - ANS - Kw is always.....
\3 Parts of the Kinetic Theory - ANS - 1. Gas Particles are small spheres with
insignificant volume
2. Motion is rapid, random, and constant
3. Collisions between particles are elastic
\Acid dissociation constant (Ka) - ANS - Ratio of dissociated ions to
undissociated ions
Ka values only exist for weak acids
Ka are constant values that are specific for each acid
\Acid-Base indicators - ANS - Exhibits color change in presence of an acid or
base
Gives estimate of pH of solution
\Acidic solution - ANS - [H+] > [OH-]
[H+] > 1.o x 10 -7
\Activity Series - ANS - A list of metals in order of deceasing reactivity. A reactive
metal will replace any metal listed below it in the activity series, only when
reactant A is a metal
\Actual Yield - ANS - Amount of product formed when performing the reaction in
the lab
\Alkaline solutions - ANS - Basic solutions are always known as .....
\Allotropes - ANS - Two or more different forms of the same element in the same
physical state. Very different properties from one another, and includes only a few
elements. Examples include diamond, graphite, and fullerene
\Amorphous solid - ANS - No order or repeating pattern. Examples include rubber,
plastic, and glass
\Aqueous solution - ANS - Water that contains dissolved substances
\Arrhenius acid - ANS - dissociate in water producing hydrogen ions
\Arrhenius Base - ANS - Dissociate in water producing hydroxide ions
\Atmospheric pressure - ANS - Results from collisions of atoms and molecules in
air with objects
\Barometer - ANS - A device used to measure atmospheric pressure. Pressure
exerted from atmosphere onto mercury pool, pushed mercury up sealed column,
read height of mercury in column. Height of mercury in column indicates
atmospheric pressure
\Base dissociation constant (Kb) - ANS - Ratio of the dissociated ions to the
undissociated ions
, Kb values only exist for weak bases
Kb are constant values that are specific for each acid
\Bases - ANS - Bitter
Slippery
unreactive with metals
Electrolytes
\Basic solution - ANS - [OH-] > [H+]
[OH-] > 1.0 x 10 -7
\Boiling point - ANS - Temperature at which the vapor pressure of the liquid
equals the atmospheric pressure
\boiling point elevation - ANS - boiling point of solution > boiling point of pure
solvent
\Bronsted- Lowery acid - ANS - Substance that can donate H+ ions
\Bronsted-Lowery base - ANS - substance that can accept H+ ions
\Buret - ANS - A cylindrical glass tube used to deliver variable volumes of
solutions for a titration
\Calculating mass to mass conversions - ANS - Convert to moles, then convert to
new substance, then convert back to mass
\Calorie - ANS - quantity of heat needed to raise the temperature of 1g of pure
water of by 1 degree celcius
\Calorimeter - ANS - Insulated device used to measure the absorption or release
of heat in chemical or physical processes
\Calorimetry - ANS - Precise measurement of heat flow into or out of a system for
chemical and physical processes
\Chemical equilibrium - ANS - The rate of the forward reaction = the rate of the
reverse reaction, which is known as a state of balance
\Chemical potential energy - ANS - energy or heat stored in the chemical bonds of
a substance
\Colligative property - ANS - Property that depends only on the number of solute
particles but not their identity
\Combination Reaction - ANS - 2 or more substances react to form a single new
substance
A + B = AB
\Combustion Reaction - ANS - Element or compound that reacts with oxygen
producing energy in the form of heat and light
Products are usually carbon dioxide and water
\concentrated solution - ANS - solution containing a large amount of solute
\concentration - ANS - A measure of the amount of solute that is dissolved in a
given amount of solvent
