Part A
The chart below lists six stars. Research the luminosity, distance from Earth, and surface temperature of
each star. Make sure to research credible sites, such as nasa. gov, to complete your chart. Distances
should be given in light years and temperatures given in Kelvin, Luminosity (L) is how bright something is
in human eyesight. As you conduct your research, look for the luminosity of each star relative to the Sun
(Therefore, the luminosity of the Sun is 1), If your sources give a fraction for luminosity, convert the
fraction into a decimal
number. Use your research to complete the chart,

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
