Aballoon that contains 0.750 moles of gas has a volume of 16.8 l. if additional gas causes the balloon to expand to a volume of 25.4 l at a constant pressure and temperature, how many moles of gas does the balloon now contain?

the answer is 1.13 moles

they must be certified by the avma. ( a.)

mark me the branliest.

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.
