White vinegar is an aqueous solution that is 0.81 M acetic acid (CH3COOH). White vinegar has a pH = 2.42 at 25°C.

a) (1 point) Write out the ionization reaction for acetic acid in water.

b) (2 points) Determine the Ka of acetic acid.

c) (2 point) Determine the pKa of acetic acid.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
