Question

what are the products of step 1 of the hydrogen fusion process in the sun? check all that apply. energy helium hydrogen a neutrino a positron mark this and return save and exit next

Explanation:

In the first - step of hydrogen fusion in the Sun (the proton - proton chain), two hydrogen nuclei (protons) combine. One of the protons is converted into a neutron through a process that emits a positron and a neutrino. Energy is also released in the process. Helium is not a product of the first step but forms in later steps. Hydrogen is a reactant, not a product of the first step.

Answer:

a positron, a neutrino, energy
