All atoms except H and O are balanced.
The oxidation number of Cl changes from 7 to 3. The change in the oxidation number is 4.
The oxidation number of O changes from -1 to 0. The change in oxidation number per O atom is 1.
Total change in the oxidation number for 2 oxygen atoms is 2.
To balance the increase in oxidation number with decrease in the oxidation number, multiply H

The oxygen atoms are already balanced.
This is the balanced chemical equation
This is primarily due to the large increase in the volume that the gas molecules themselves occupy.
<h3>How is the ideal gas equation defined?</h3>
The ideal gas equation is PV = nRT. P represents for the ideal gas's pressure, V for its volume, n for its total mass, expressed in moles, R for its gas constant, and T for temperature in this equation.
<h3>the author of the ideal gas equation?</h3>
The pressure, volume, heat, and quantity of an ideal gas are all related by a single equation that was created through the experimental work of multiple people, including Robert Boyle, Pierre A. C. Charles, and Joseph Gay-Lussac. Boyle's Law states that as pressure decreases, gas volume increases.

Answer:
A. volume
Explanation:
Generally the equation for the ideal gas is mathematically given as
PV=nRT
Where
P=pressure
V=volume
R=gas constant
n=Number of Moles
T=Temperature
Therefore
V=nRT/P
Option A

Answer is: The highest occupied s and p sublevels are completely filled.
Noble gases (group 18) are in group 18: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn). They have very low chemical reactivity.
Noble gases have very stable electron configuration and does not need to gain electrons, only when they gain energy.
1) For example, krypton is a chemical element with symbol Kr and atomic number 36, which means it has 36 protons and 36 electrons.
Electron configuration of krypton atom:
₃₆Kr 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶.
2) Another example, xenon (Xe) is noble gas with atomic number 54, which means it has 54 protons and 54 electrons.
Electron configuration of xenon atom:
₅₄Xe 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 5s² 5p⁶.
