Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

Define dependent variable.
The factor that is being measured.
Where is the independent variable found on a graph?
X axis
After a supernova for a super massive star, what is the next phase?
black hole
What is the charge of C-14?
0
What is cosmic soup?
At the beginning of the universe, it was too hot for matter to form, so protons, neutrons, and electrons were a mixture called "cosmic soup."
During which phase of an average star's life cycle would you find more nitrogen atoms? How do you know?
black dwarf; the star has cooled, so fusion of larger atoms can occur
How does the red shift of light support the Big Bang Theory?
The red shift provides evidence for the expansion of the universe.
Which type of stars are the hottest?
massive stars
Which type of stars burn through their fuel more quickly?
massive stars
How is the charge of an atom determined?
atomic # - # e- or # p+ - # e-
When does He fusion occur during a star's life cycle?
red giant/ red supergiant phase
When does H fusion occur during a star's life cycle?
protostar/ main sequence stage
When did the solar system form?
4.6 billion years ago
When did the universe begin?
13.7 billion years ago
In basic terms, describe the Big Bang Theory.
The universe is expanding and cooling.
How does the presence of large amounts of helium in the universe support the Big Bang Theory?
Large amounts of helium provide evidence that the universe was really hot.
What makes up a solar system?
Star and anything orbiting around it
What is a galaxy?
A large formation of stars surrounding a black hole.
Based on the following chemical equation, list the reactants: A + B --> C + D
A, B
How are the atoms in a chemical reaction changed?
rearranged
How is a compound different from a molecule?
A compound combines atoms from 2 or more DIFFERENT elements, whereas a molecule combines 2 or more atoms from ONE or more elements.
What is an isotope? Give an example.
Atom with a different number of neutrons. C-14
How is atomic mass determined?
Bottom # on the periodic table; Top number for nuclear notation; add protons and neutrons
Where are each of the subatomic particles found in an atom?
p+ and n found in nucleus; e- found in cloud around nucleus
What are the three subatomic particles and their respective charges?
proton (+), neutron (neutral), electron (-)
