1. A mixture containing 5.34 g each of CH4(8) CzH4(e) and C4H10(e) is contained in a 3.45 - L vessel at a temperature of 88 oC ( calculate the partial pressure of each of the gasses in the mixture. (calculate the total pressure of the mixture​

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.
