## Section

STIOCHIOMETRY:Refers to quantitive measurements & relationships involving substances & mixtures of chemical interest.
MOLECULAR FORMULA: Denotes the numbers of the different Atoms present in a molecule.
EMPIRICAL FORMULA:Is the simplest chemical formula that can be written for a compound, that is having the smallest integral subscripts possible.
ELECTROLYTE:Is a substance that provides Ions when dissolved in water (H20)
MOLECULAR REACTION EQUATION:Is a balanced chemical reaction equation, where the ionic compoumds are expressed as molecules instead of componet Ions.
COMPLETE IONIC REACTION EQUATION:Is a chemicsl equation where the electrolytes in an aqueous solution are written as dissociated Ions.
SPECTATOR ION: Are ionic species that are present in a reaction mixture but, do not take part in the reaction.
ARRHENIUS ACID:Is a substance that when added to water (H2O) increases the number of (H+) Ions in the water.
ARRHENIUS BASE:Is a substance that dissociates in water to form hydroxide (OH-) Ions. *Increases concentration of (OH-) Ions in aqueous solution.
BRONSTED ACID:(PROTON H+ION DONOR) The conjugate acid is the species cteated when a base accepts the PROTON.
BRONSTED BASE:(PROTON H+ION ACCEPTOR)The conjugate BASE Ion\Molecule remaining after the acid has lost it's protons.
LIMITING-REACTANT(REAGENT):In a reaction is the reactant that ia consumed Cop lately
MOLARITY:The number of moles of solute, the material dissolved, per liter of solution
DILUTION:The action of making a liquid more dilute, making it weaker in force, content or value.
TITRATION:Is a procedure for carrying out a chemical reaction between two solutions by the controlled addition of one solution to the other.
VAPOR:A substance diffused\suspended in the air, especially one normally liquid\solid.
GAS:Atoms\Molecules are generally much more widelt seperated than in liquids & solids. A gas assumes the shape of it's container, thus having neither define shape\volume
PRESSURE:Is a force per unit area. Applied to gases: pressure is most easisly understood in terms of height of a liquid column that can be maintained by the gas.
BOYLE'S LAWThe volume of a fixed amount of gas at a constant temperature.
