A 9.75 L container holds a mixture of two gases at 15 ° C. The partial pressures of gas A and gas B, respectively, are 0.415 atm and 0.542 atm. If 0.100 mol of a third gas is added with no change in volume or temperature, what will the total pressure become?

a is the correct answer

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.
