Based on Redox Titration, what do you suggest for titration of iron()? Choose the titrant Determine the oxidation and reducing agents Write the half-equations Balancing the Redox reaction Choose a suitable indicators Description of the type of redox titration (direct or back titration, the medium used, color changes..)

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.
