Two unknown compounds made of P and Cl are tested. Compound 1 contains 3.097g of phosphorus and 10.63 g of chlorine. Compound 2 contains 1.548 g of phosphorus and 8.863g of chlorine. Show that this
experimental data follows the law of multiple proportions

12 is it do you think so

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.
