equilibrium constant (Keq) -ANSWER-numerical value that characterizes the
relationship between the concentrations of reactants and products in a system at
chemical equilibrium
equilibrium expression -ANSWER-wA + xB <---> yC + zD
Keq = products with coefficient as power multiplied/ reactants with coefficient to
the power mulitplied
Le Chatelier's Principle -ANSWER-states that when a stress is applied to a system
in equilibrium, the system will readjust in the direction that best reduces the
stress imposed on it
effects on equilibrium reaction -ANSWER-increased concentration shifts away
form added component to the reactant sideincreased temp. will change
depending on temp. to productincreased pressure shifts away from added gas
chemical reaction rate -ANSWER-rate at which reactants are consumed or
products produced in a given time period in a chemical reaction
chemical kinetics -ANSWER-study of reaction rates
,factors affecting rates of reactions -ANSWER-nature of reactant
concentration - the higher the more
collisions
temperature
catalyst
catalysts -ANSWER-substance that increases a chemical reaction rate without
being consumed in the reactionthey do not change equilibrium
equilibrium reaction -ANSWER-a state in which the rate of the forward reaction
equals the rate of the reverse reaction
reversible reaction -ANSWER-a reaction that can go either way <---->
solute -ANSWER-is dissolved
solvent -ANSWER-does the dissolving
H20 is the universal solvent
Chemistry -ANSWER-the science of materials their composition structure and
changes they undergo
Matter -ANSWER-anything with mass and takes up space
,substance -ANSWER-a homogeneous material consisting of one particular kind of
matter
physical states of matter - solid -ANSWER-definite shape and volume
physical states of matter - liquid -ANSWER-indefinite shape and definite volume
Physical states of matter - gas -ANSWER-indefinite shape and indefinite volume
physical properties -ANSWER-color, crystalline, melting point , boiling point ,
refractive index
chemical properties -ANSWER-characteristic of a substance that describes the
way the substance undergoes or resists change to form a new substance
physical change -ANSWER-change of state
chemical change -ANSWER-different substances with new properties formed
heterogenous mixture -ANSWER-contains visibly diffferent phases , different
properties
homogeneous mixture -ANSWER-contains only one visibly distinct phase
element -ANSWER-substance that cant be decomposed by chemical means
identical atoms
, compounds -ANSWER-can be decomposed into two or more simpler substances
by ordinary chemical means
diatomic molecules -ANSWER-seven elements that when in their natural states
are always pairs
H2 N2 O2 F2 Cl2 Br2 12
accuracy -ANSWER-refers to the correctness of measurement data
precision -ANSWER-refers to the reproductibility of measurement data
scientific notation -ANSWER-smaller than one = negative exponent
larger than one = postive exponent
density -ANSWER-mass/volume
temperature -ANSWER-K = C + 273
C = K - 273
law of conservation of matter -ANSWER-states that matter can be neither created
not destroyed
creator of law of conservation of matter -ANSWER-antoine laurent lavoisier
