- Problem:
- The sun's energy is generated by a series of fusion reactions known as the proton-proton cycle.
-
- (13) In the first step of the cycle, two protons fuse together, forming three products. What are the total mass and charge of these particles?
-
- Both mass and charge are conserved, so the products must have mass of approximately 2 amu and charge of +2. The actual reaction looks like
