shown in the table. Which favors products the
most? Which favors products the least? Rank
these systems in order from most to least in terms
of favoring products rather than reactants.

the answer is na (sodium)

i think it's letter a.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
