A student prepares a aqueous solution of acetic acid . Calculate the fraction of acetic acid that is in the dissociated form in his solution. Express your answer as a percentage. You will probably find some useful data in the ALEKS Data resource. Round your answer to significant digits.

The question is incomplete , complete question is ;

A student prepares a 0.30 mM aqueous solution of acetic acid . Calculate the fraction of acetic acid that is in the dissociated form in his solution. Express your answer as a percentage. The

21.43% is the percentage of acetic acid that is in the dissociated form in its solution.

Explanation:

The value of acetic acid = 4.756

The dissociation constant of acetic acid =  

The initial concentration of acetic acid = c = 0.30 mM =

Degree of dissociation of acetic acid =

initially

c       0    0

At equilibrium

(c-cα)      cα   cα

The expression of dissocation constant :

21.43% is the percentage of acetic acid that is in the dissociated form in its solution.

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.
