practice: label the reactants, yield, and products of the chemical equations below:

agno3 + h2s → ag2s + 2hno3
al + n2 → 2 aln
h2so4 + nacn → hcn + na2so4
kclo3 → kcl + o2

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.  

yes the answer is total mass in unchanged   : )
