Question 22 (Mandatory) (1 point) Why does the compound ammonium hydroxide not form when ammonium chloride
reacts with sodium hydroxide?
a) Ammonium hydroxide does not exist.
b) Ammonium hydroxide readily decomposes to ammonium ions and hydroxide
ions.
c) Ammonium hydroxide readily decomposes into ammonia gas and water.
d)
Ammonium hydroxide is stable, but reacts with the excess ammonium
chloride to form a complex ion.
e) The reaction does not occur.

explanation:

the correct answer is:

a. formation of precipitation

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

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.
