Cho phản ứng: C6H6+15/2O2-> 6O2+3H2O ở 300K có QP – QV =1245J. Hỏi C6H6 và H2O trong phản ứng ở trạng thái lỏng hay hơi?

the answer is c i took the test

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.
