Chem 101 final
exam questions
and answers
Ionic Compound - answer a compound composed
of positive and negative ions that are combined so
that the numbers of positive and negative charges
are equal
Covalent Compound - answer a chemical
compound formed by the sharing of electrons
The Ideal Gas Law - answer PV = nRT.
Tells you how a gas responds to a change in its
physical conditions. change P, V or T, and the
others adjust
Stoichiometry - answer that portion of chemistry
dealing with numerical relationships in chemical
reactions; the calculation of quantities of
substances involved in chemical equations
, Electrolytes - answer chemical substances that
develop an electric charge and are able to conduct
an electric current when placed in water; ions
Strong Acids - answer HCl, HBr, HI, HNO3, HClO4,
H2SO4
Dissociates completely in water
Weak Acids - answer HF, HCN, HC2H3O2, H2S,
H2CO3, HClO
Doesn't dissociate completely in water
Net Ionic Equation - answer an equation for a
reaction in solution showing only those particles
that are directly involved in the chemical change
Spectator Ions - answer ions that do not take part
in a chemical reaction and are found in solution
both before and after the reaction
Acid - answer a substance that increases the
hydrogen ion concentration of a solution
Base - answer eat protons
consume H+ ions when fin water
