write a complete ionic equation and a net ionic equation for what occurs when a saturated solution of potassium sulfide (K_(2)S) is mixed with a saturated solution of chromium (III) nitrate (Cr(NO_(3))_(3)), given that the sulfides of all transition metals are only sparingly soluble and that all nitrates are soluble.

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.
