Wow, now this one is a hard one, took me quite a while to figure it out but here it is:
The abundances of the two isotopes is:
Antimony-121 = 57.2%
Antimony-123 = 42.8%
The abundances of the two isotopes is:
Antimony-121 = 57.2%

A Resonance structure is the Lewis structure of every atom in the molecule, that gives one Lewis structure. But they called it resonance structure to have a change.
There is 7 resonance structures for SO3, like the images below:

Answer:
548s = t
Explanation:
A first-order reaction has as general equation:
Where is the concentration of the reactant in the time t,
is the initial concentration of the reactant, k is rate constant and t is time. Replacing with values of the problem:
-1.65 = -3.00x10⁻³s⁻¹×t
<em>548s = t</em>

I hope it helps!
