Answer:
1984
Explanation:
Given the formula;
0.693/t1/2 = 2.303/t log (Ao/A)
Where;
t1/2 = half life of the radioactive isotope
t= age of the wine
Ao= initial activity of the wine
A= activity of the at time = t
0.693/12.3 = 2.303/t log (5.5/0.688)
0.693/12.3 = 2.079/t
0.056 = 2.079/t
t= 2.079/0.056
t= 37 years
The wine was produced 37 years ago which means that it was produced in the year 1984
The balanced equation is,
OBz-(aq) + H2O(l) ---> HOBz(aq) + OH-(aq)
The equation for Kb is :
Kb = [HOBz][OH-]/[OBz]
<h3>What do we know about benzoate ion?</h3>
The conjugate base of benzoic acid, benzoate is the simplest member of the family of benzoates. It consists of a benzoic acid core with a proton missing to give it a charge of -1. It serves as a xenobiotic metabolite for humans as well as a metabolite for plants. It is a benzoic acid's conjugate base.
