Formic acid is as a preservative and antibacterial agent in livestock feed. The pKa of formic acid is 3.75. What is the reaction of formic acid (CH2O2) with water

catya your not at all which answer i've seen you do this on another question!

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.
