Renewable energy sources - hydroelectric power
include: - geothermal power
- solar power
In the U.S. the primarycombustion of fossil
fuels energy source used to generate electricity is:
Einstein's equation E = mc2 energy
means that matter can be
converted into:
Which of the following - Energy is released during nuclear fission.
options correctly describe - During nuclear fission, a large nucleus splits intosmaller ones.
the process of nuclear
fission? Select all that apply.
During nuclear fission, the lower, released
mass of the products is
slightly _____ than the mass
of the reactants. This mass
difference accounts for the
energy _____ by the
reaction.
Renewable energy sources
continually and rapidly replenished from natural sources
are:
,T/F:Most of the electricity False
generated in the U.S. is
produced from nuclear
power.
Which of the following - This equation shows that matter can be convertedinto
options correctly interpret energy
and explain the equation E =
mc2? Select all that apply. - This equation can be used to explain how a
nuclearreaction produces energy.
- The symbol c in this equation represents the speedof light.
The process during which a fission
large nucleus is split into
smaller ones is called nuclear
_____.
How does the process of Mass of the reactants is converted into energy, which is
nuclear fission produce released.
energy?
Which of the following - the size of the nucleus
factors determine whether or - The number of protons in the nucleus
not a nucleus will undergo
nuclear fission?
Select all that apply.
How many protons and 17 protons; 20 neutrons
neutrons are found in
chlorine-37?
Which of the following - The number 86 is the atomic number of the isotope.
options correctly interpret - 86 represents the number of protons in the nucleus.
the symbol Rn224/86? -Rn is the symbol of the element.
Select all that apply.
false
True or false: A nuclear - reason: In a chemical equation the atoms must balance. In a
equation is balanced in the
nuclear equation the atoms do not balance, since one nucleus
same way as any other
chemical equation. is converted into another.
Instead, the protons and neutrons will balance.

Which of the following - Small nuclei are less likely to undergo fission.- The number of
options correctly describe the protons and neutrons influence the ability of a nucleus to
factors that influence the
ability of a nucleus to undergo fission.
undergo fission? Select all - Heavy nuclei may undergo fission if bombarded withhigh-
that apply. energy neutrons.
Only the neutrons that are 1
produced should be shown in
a nuclear fission equation
because it is assumed that
_____ initiates the nuclear
reaction.
How many neutrons are in 5
the carbon-11 isotope?
Which of the following - A chain reaction is one that becomes self-sustaining. - In a
options correctly describe a chain reaction, one of the reaction products is recycled as a
chain reaction? Select all that reactant.
apply.
