Given the following information: Red giants derive their energy not from nuclear fusion of hydrogen, but by fusion of helium. Specifically, a reaction where 3 helium nuclei fuse into 1 carbon nucleus.

The mass of a helium nucleus is 6.645x10-27 kg, and the mass of a carbon nucleus is 1.9922x10-26 kg
The mass-energy relation is famously: E = mc2

1) This is the mass that is converted into energy, and we can figure out how much energy that is by using Einstein's famous equation:

E = mc2
c = 3 x 108 m/s
Plug the mass difference (∆m) into the equation above, and find the energy released in units of Joules (1 J = 1 kg*m2/s2).

Submit your answer as the coefficient (Y) of the below scientific notation expression:

Y x 10-12 Joules per one fusion reaction

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
