Goog Tuantity of Roare Combined with 3.44g of Macle according to this Chemical vonetion:
9 Rb + Mach
Mg + 2 Roce
What mass of Mo is formed and what mass of what reactans is
last over?

neutrons are in the middle of the atom and the electrons, which are much smaller.

b is the correct

let that person have a turn to speak : )

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.
