WILL GIVE BRAINLIEST !! What is the process of solar nuclear fusion?
Hydrogen atoms are fused into deuterium, then helium-3, then helium-4, each step giving off large amounts of energy.
Hydrogen atoms are fused into deuterium, then helium-4, then back into hydrogen, each step giving off large amounts of energy.
Helium molecules are fused together and become hydrogen molecules giving off large amounts of energy.
Hydrogen molecules are fused together and become oxygen molecules giving off large amounts of energy.

the third one,"Helium molecules are fused together and become hydrogen molecules giving off large amounts of energy."

Explanation:

Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.

dear miss layla

while looking through books for my class period i noticed the library cards in the books.most of them are torn or have no space to write out our names anymore.would we be able to replace them?

and your question what topic are you in trouble with?
