The molar volume of an ideal gas at 21.5 oc is listed in the background section of the lab manual as 24.179 l/mol. compare your measured value in the first part of the experiment to the listed value by calculating the experimental error from the second part of the experiment according to the formula below. choose the closest answer. % error = |experimental molar volume - listed molar volume| / (listed molar volume) x 100

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.
