Term
Chemical Equilibrium
Definition
the rate of forward reaction is equal to the rate of the reverse reaction
Term
Dynamic Equillibrium
Definition
both the forward and reverse proccess are still occuring but at equal rates
Term
product-favored reactions
Definition
reactions in which reactants are completely or largely converted to products when equlibrium is reached
Term
reactant favoured
Definition
the opposite of product-favored reactions the reactions lead to the conversion of only a small amount of the reactants to products
Term
solution
Definition
homogenous mixture of two or more substances
Term
Solvent
Definition
the median in wich the solute is dissolved
Term
solute
Definition
the dissolved sobstance
Term
aqueos solutions
Definition
solutions in which water is the solvent
Term
electrodes
Definition
conductor of electricity 
Term
strong electrolyte
Definition
substances whose solutions are good electrical conductors owing to the presence of ions
Term
non electrolytes
Definition
compunds who aqeous solutions do not conduct electricity 
Term
weak electrylites
Definition
when the compund is disolved in water only a small fraction of the kolecules forms ions.
Term
exchange reactions
Definition
the ions of the reactants exchange partners
Term
precipation reaction
Definition
produces a water insoluble solid product called a precipate
Term
precipate
Definition
a water insoluble solid product

Definition
oxides that can react with water to produce H3O+
Term
basic oxides
Definition
oxides of metal that give basic solutions when dissolved in water
Term
reducing agent
Definition
the agent that brings about the reduction
Term
oxidizing agent
Definition
the agent responsible for oxidation
Term
oxidized
Definition
when a substance loses electrons
Term
oxidation number 
Definition
the charge an atom has or appears to have 
Term
Each atom in a pure elemnt has an oxidation number of zero
Definition
Term
For monatomic ions, the oxidation number is equal to the charge on the ion
Definition
Term
When combined with another element, flourine always has an oxidation number of -1
Definition
Term
The oxidation number of O is -2 in most compounds
Definition
Term
Cl, Br, and I have oxidation numbers of -1 in compounds, except when combined with oxygen and flourine
Definition
Term
The oxidation number of H is +1 in most compunds
Definition
Term
The algebraic sum of oxidation numbers for the atoms in a neutral cmpound must be zero; in a polyatomic ion, the sum must be equal to the ion charge.
Definition
Term
precipitation reactions
Definition
ions combine in solution to form an insoluble reaction product
Term
acid-base reactions
Definition
water is a product og many acid-bae reactions, and the cation of the base and the anion of the acid form a salt
