First, we need to get no.of moles of acetic acid = molarity * volume
= 0.3 m * 0.5 L
= 0.15 moles
then, we need to get no. of moles acetate = molarity *volume
= 0.2m * 0.5L
= 0.1 moles
and we have also to get moles of NaOH = molarity * volume
= 1 m* 0.02L
= 0.02 moles
according to the reaction equation and by using ICE table:
CH3COOH + OH- → CH3COO- + H2O
∴ moles acetic acid = 0.15 - 0.02 = 0.13 moles
when [acetic acid] = moles / total volume
= 0.13 moles / (0.5L + 0.02L)
= 0.25 M
and moles of acetate = 0.1 + 0.02 = 0.12 moles
∴[acetate] = moles / total volume
= 0.12 moles / 0.52L
= 0.23 M
and when we have the value of Ka so we can get the Pka from this formula:
Pka = -㏒ Ka
= -㏒ 1.8 x 10^-5
= 4.7
by using H-H equation we can get the PH:
∵PH = Pka + ㏒[acetate] /[acetic acid]
∴PH = 4.7 + ㏒(0.23 /0.25]
= 4.66

The nuclear fission reaction with the formation of the deuterium has the missing part as ⁴₂He.
<h3>What is nuclear radiation?</h3>
Nuclear radiation is given as the reaction in which the emission is formed in the form of the nuclear particles that made the change in the nucleus of the atom.
The nuclear radiation that made the release of ₁¹H can be given to fuse the electron with the He and form:
²₁H + ³₂He →⁴₂He + ₁¹H
Thus, the missing part in the nuclear fission reaction is ⁴₂He.
