Two different compounds are formed by the elements nitrogen and oxygen. the first compound, compound p1, contains 64.17% by mass nitrogen and 35.73% by mass oxygen. the second compound, compound p2, contains 47.23% by mass nitrogen and 52.79% by mass oxygen. what is the ratio of nitrogen to a fixed mass of oxygen for the two compounds?

explanation:

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.
