Our current periodic table lists 118 elements.
Is it possible that there are still any
undiscovered elements in between the elements listed in the periodic table?
A) Yes, but to avoid detection for this long
they would have to exist in very small quantities or not occur on Earth at all.
B) Yes, but they would have to be totally
non-reactive so they are never found in
compounds.
C) Yes, but they would have to be radioactive
with extremely short half lives so they
decay before they can be detected.
D) No, because all the boxes in the periodic
table are already filled.
E) No, because the atomic number is the
number of protons in the nucleus and we
have accounted for all possibilities from 1
through 118.
what is E?
(there may be elements beyond 118, but there is never going to be an element 117.5)
According to the Arrhenius definition of acids
and bases, is carbon dioxide an acid, a base, or
neither?
A) Neither, because CO2 does not contain H
or OH in its chemical formula.
B) Neither, because CO2 does not have the
words "acid" or "base" in its name.
C) Neither, because CO2 is a covalent
compound.
D) It is a base, because when you dissolve it
in water the pH goes up.
E) It is an acid because when you dissolve it
in water the pH goes down.
what is an acid because when you dissolve it in water the pH goes down?

According to natural selection, which would occur if
a phenotype in 1 out of 100 organisms provided an
advantage for acquiring food and reproducing?

B) Organisms with that phenotype would thrive and
the allele(s) for that phenotype would increase in
the population over time.
C) The phenotype in the population would remain
relatively stable.
D) After several generations, the phenotype would
still represent 1% in the population.
E) Since it is only 1% of the population, organisms
with that phenotype would fail to pass on any
useful genes.
what is B?

In a mercury thermometer, why does the
mercury level in the tube go up as the
temperature increases?
A) Because that's how thermometers work.
B) Because heat rises, so as the mercury
warms up it rises up the tube.
C) Atoms expand in size as they are heated,
increasing the volume of the mercury in
the tube.
D) The mercury atoms move farther apart as
the temperature increases, increasing the
volume of the mercury in the tube.
E) Some mercury at the bottom of the tube
begins to boil, pushing the mercury above
it higher up the tube.
