Chemical Reactions - Answer: the organization of atoms in one or
more substances
the bonds are broken and formed, with the same number of
atoms on each side of the arrow
, stoichiometry - Answer: a mathematical means of getting from
one unit to another (utilizing a chemical equation)
dependent on: nature of the reaction - the exact nature of the
chemicals when dissolved
-amount of chemicals present- molarity
stoichiometric mixture - Answer: one that possesses equivalent
amounts of reactants that match the numbers in the balanced
equation
limiting reagent - Answer: determines the amount of product
formed. The reactant that runs out first and thus limits the
number of products that can be formed. stoichiometry and
balanced equation are used.
hydration - Answer: interaction between H2O molecules and ions
of salt, causing dissolution
broken into cations and anions
solubility - Answer: depends on the attraction of ions to one
another and the attraction of ions to H2O molecules
many nonionic solids are soluble
