electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal).
17.8 g of sodium perchlorate contains 8.73 × 10²² Na⁺ ions, 8.73 × 10²² ClO₄⁻ ions, 8.73 × 10²² Cl atoms and 3.49 × 10²³ O atoms.
First, we will convert 17.8 g of NaClO₄ to moles using its molar mass (122.44 g/mol).

Next, we will convert 0.145 moles to molecules of NaClO₄ using Avogadro's number; there are 6.02 × 10²³ molecules in 1 mole of molecules.

NaClO₄ is a strong electrolyte that dissociates according to the following equation.
NaClO₄ ⇒ Na⁺ + ClO₄⁻
The molar ratio of NaClO₄ to Na⁺ is 1:1. The number of Na⁺ in 8.73 × 10²² molecules of NaClO₄ is:

The molar ratio of NaClO₄ to ClO₄⁻ is 1:1. The number of ClO₄⁻ in 8.73 × 10²² molecules of NaClO₄ is:

The molar ratio of ClO₄⁻ to Cl is 1:1. The number of Cl in 8.73 × 10²² ions of ClO₄⁻ is:

The molar ratio of ClO₄⁻ to O is 1:1. The number of O in 8.73 × 10²² ions of ClO₄⁻ is:

17.8 g of sodium perchlorate contains 8.73 × 10²² Na⁺ ions, 8.73 × 10²² ClO₄⁻ ions, 8.73 × 10²² Cl atoms and 3.49 × 10²³ O atoms.

Answer: entropy
Explanation:
Entropy is the measure of degree of randomness or disorder of the system.
Bond energy is the energy possessed by a substance by virtue of its bonding of electrons
Enthalpy is the amount of energy absorbed or released in a chemical reaction.
Internal energy is the energy possessed by a body by virtue of rotational, vibrational and transitional modes.
Heat flow is the phenomenon of thermal equilibrium in which heat flows from hotter body to colder body to maintain equilibrium temperature.
Answer:
The molarity of KOH = 0.86M
Explanation:
From the equation of reaction
2KOH(aq)+H2SO4(aq)→K2SO4(aq)+2H2O(l)
nA= 1, nB=2
From the question
CA= 1.5M, VA= 17.2ml, VB= 60ml, CB= ?
Applying (CAVA)/(CBVB) = nA/nB
(1.5×17.2)/(CB×60) = 1/2
Simplify
CB= (1.5×17.2×2)/(60×1)
CB = 0.86M
