The formation of FeSCN2+ in an aqueous solution is represented by the chemical equilibrium shown below. A light red-brown solution is prepared combining 12.50mL of Fe(NO3)3.0.5mL of 0.002M KSCN and 37.OmL of water that had been slightly acidified. If an additional of 0.5M Fe (NO3)3 is added, which of the following predicts and explains correctly whether the darkness of the color of the solution will change?

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.
