Question

fission and fusion are two types of reaction.
a nuclear
b chemical
in the sun, mass is converted to.
a particles
b energy
what new atom is created in the solar nuclear fusion?
a hydrogen
b helium

Explanation:

1. Fission and fusion involve changes in the nucleus of atoms, so they are nuclear reactions. Chemical reactions involve only the electrons outside the nucleus.
2. According to Einstein's mass - energy equivalence (E = mc²), in the sun's nuclear reactions, mass is converted into energy.
3. In solar nuclear fusion, hydrogen atoms combine to form helium atoms through a series of reactions.

Answer:

1. A. nuclear
2. B. energy
3. B. Helium
