Stoichemistry & Types of Chemical Reactions
Question:
reactants
Answer:
substances undergoing reaction placed on the left side of the equation
Question:
products
Answer:
substances generated by the reaction placed on the right side of the equation
,Question:
what is the requirement an equation must satisfy to be consistent with the law
of conservation of matter?
Answer:
it must be balanced on the reactant and product sides
Question:
spectator ions
Answer:
ions whose presence is required to maintain charge neutrality—are neither
chemically nor physically changed by the process
Question:
precipitation reaction
Answer:
dissolved substances react to form one (or more) solid products
,Question:
solubility
Answer:
the maximum concentration of a substance that can be achieved under
specified conditions
Question:
when does a substance precipitate?
Answer:
when solution conditions are such that its concentration exceeds its solubility
Question:
what type of substances readily precipitate from solution?
Answer:
insoluble
Question:
acid-base reaction
Answer:
one in which a hydrogen ion, H+, is transferred from one chemical species to
another
, Question:
acid
Answer:
a substance that will dissolve in water to yield hydronium ions, H3O+
Question:
strong acids
Answer:
completely react with water
Question:
weak acids
Answer:
only partially react with water, leaving a large majority of dissolved molecules
in their original form and generating a relatively small amount of hydronium
ions
