A sample of a yellow gas is in a container, as shown below. Volume = 2L
Pressure = 0.5 atm
Temperature = 300 K
Using the information in the graphic and the equation PV = nRT, calculate the number of moles of gas in the sample.

answerto predict;

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.
