(b)which student measured density with the greatest accuracy?Explain your answer

passing a magnet thought the

mixture , because iron gets attracted to magnet .

the answer is c i believe

the dissolution of polymer can be thermodynamically described in 2 steps.

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.
