<h3>Further explanation</h3>
Given
Fluorine-18
Oxygen-18
Required
Nuclear equation
Solution
Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,
- alpha α particles ₂He⁴
- beta β ₋₁e⁰ particles
- gamma particles ₀γ⁰
- positron particles ₁e⁰
- neutron ₀n¹
The principle used is the sum of the atomic number and mass number before and after the decay reaction is the same
The reaction
₈O¹⁸ + ₁¹H(proton) ⇒ ₉F¹⁸ + ₀n¹(neutron) + ₀γ⁰
(gamma)
We expect the release of PCO2 from the bottle, When the cork is pulled.
<h3>What do you expect to happen?</h3>
When the cork is pulled, we expect the release of PCO2 in the atmosphere to happen because there is high concentration of PCO2 in the bottle but there is no concentration of PCO2 in the atmosphere so due to diffusion, the PCO2 gas moves outside the bottle.
So we can conclude that When the cork is pulled, the release of PCO2 from the bottle will be expected.

Answer:
Option D) A transition state and a reaction intermediate are the same.
Explanation:
A transition state and a reaction intermediate are the not same. The transition state represents the highest energy in the steps of a reaction, whereas an intermediate, on the other hand, is represented by the lowest energy minimum in a reaction.
