CHEM 121 FINAL EXAM! NEWEST EXAM WITH MULTIPLE CHOICE OF
QUESTIONS AND CORRECT ANSWERS ALREADY GRADED A+ AND 100%
GUARANTEE PASS (BRAND NEW!!!!!!!!!)
kinetic molecular theory - CORRECT ANSWERS-all matter is made of tiny particles that
are constantly moving
fundamental particle - CORRECT ANSWERS-take a macroscopic object and divide it
repeatedly. Eventually you have a particle, which, if further divided is no longer the original
substance. This smallest piece of the substance is called...
h2o molecule - CORRECT ANSWERS-the fundamental particle of water is what?
atom - CORRECT ANSWERS-the basic unit of a chemical element
molecule - CORRECT ANSWERS-two or more atoms (same or different) chemically
bound
element - CORRECT ANSWERS-fundamental particle contains only one kind of atom
compound - CORRECT ANSWERS-two or more different kinds of atoms chemically
bound
the same - CORRECT ANSWERS-in a pure substance, all the fundamental particles are
what?
solution - CORRECT ANSWERS-mixture that is uniform throughout
density - CORRECT ANSWERS-= mass / volume
, atomic number - CORRECT ANSWERS-number of protons in the nucleus, defines the
element
mass number - CORRECT ANSWERS-equal to the sum of protons and neutrons
isotope - CORRECT ANSWERS-what results when you change the number of neutrons in
an element?
atomic mass - CORRECT ANSWERS-weighted average of the masses of the isotopes of
an element, gives the mass of one atom of the element
alkali metals - CORRECT ANSWERS-group 1 on periodic table
alkali earth - CORRECT ANSWERS-group 2 on periodic table
halogens - CORRECT ANSWERS-group 17 on periodic table
properties of metals - CORRECT ANSWERS-good conductors of heat and electricity,
malleable, ductile, often shiny, tend to lose electrons in chemical change
properties of non metals - CORRECT ANSWERS-poor conductors of heat and electricity,
not ductile, not malleable, gain electrons in chemical change
avagadros number - CORRECT ANSWERS-6.022 x 10^23
ionic bond - CORRECT ANSWERS-bond between a nonmetal and a metal
covalent bond - CORRECT ANSWERS-bond between 2 or more nonmetals
