Problem 61E

A portion of the Sun’s energy comes from the reaction

4 11H→42 He + 2 01 e

which requires a temperature of 106 to 107 K.

(a) Use the mass of the helium-4 nucleus given in Table to determine how much energy is released when the reaction is run with 1 mol of hydrogen atoms.

, (b) Why is such a high temperature required?

Step-by-Step Solution:
Step 1 of 3

THE HEART OF THE MATTER ● the lighter chemical elements are the most abundant on earth ○ the heavier (gold) = more rare ● both space and time came out of the Big Bang ● string/loop of energy is the one basic particle ● gravity doesn’t fit or work well with quantum theory ● string theory = only theory so far that reconciles Quantum Theory and gravity ○...
