A student writes the following incorrect chemical equation for a single replacement reaction be- tween hydrogen chloride and aluminum
HCI + AI CI
(aq) (s) 2 (g)
+ AIH
3 (s)
Part 1:
What is wrong with the student's prediction of the products in the above reaction?
(Hint: In a single replacement reaction, part of an ionic compound is removed and replaced by a new element.)
+

the answer is b. dilution

the answer is c. nacl

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.
