(a) Interpretation: Whether S or S 2 − is larger should be determined. Concept introduction: Atomic radius is the distance between the valence shell and the atomic nucleus. Down the group, more shells are added in successive members and the atomic radius increases. It decreases in the period as an effective nuclear charge increases.

Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.

Interpretation Introduction
(a)
Interpretation:
Whether S or S2− is larger should be determined.
Concept introduction:
Atomic radius is the distance between the valence shell and the atomic nucleus. Down the group, more shells are added in successive members and the atomic radius increases. It decreases in the period as an effective nuclear charge increases.
Interpretation Introduction
(b)
Interpretation:
Whether Ca or Ca2+ is larger should be determined.
Concept introduction:
Atomic radius is the distance between the valence shell and the atomic nucleus. Down the group, more shells are added in successive members and the atomic radius increases. It decreases in the period as an effective nuclear charge increases.
Interpretation Introduction
(c)
Interpretation:
Whether O− or O2− is larger should be determined.
Concept introduction:
Atomic radius is the distance between the valence shell and the atomic nucleus. Down the group, more shells are added in successive members and the atomic radius increases. It decreases in the period as an effective nuclear charge increases.
The kinetics of a gas phase reaction of the form A → Products results in a rate constant of 0.00781 M/min. For this reaction, the initial concentration of A is 0.501 M. How many minutes will it take for the concentration of A to reach 0.144 M
What is the rate for the second order reaction A → Products when [A] = 0.256 M? (k = 0.761 M⁻¹s⁻¹)
