It is impossible to reach absolute zero because the magnitude of work that is required to remove energy from a gas in order to attain the absolute zero is so high.
<h3>What is the absolute zero?</h3>
The absolute zero is the temperature at which the movement of all the gas molecules is theoretically believed to cease. At the absolute zero, gas molecules remain at fixed positions because according to the third law of thermodynamics, the entropy of a perfectly ordered system is zero.
It is impossible to reach absolute zero because the magnitude of work that is required to remove energy from a gas in order to attain the absolute zero is so high such that it is impractical to attain the absolute zero.

Answer:
Option A
Explanation:
An intensive property is a bulk property, meaning that it is a local physical property of a system that does not depend on the system size or the amount of material in the system. Examples of intensive properties include temperature, T; refractive index, n; density, ρ; and hardness of an object,specific heat, η.
Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, specific heat and many others.
They have 2 lone pairs and 3 bond pairings. Sp3D hybridization has been achieved in the core atom. The molecule is trigonally bipyramidal or T-shaped.
<h3>What is the name of T-shaped molecular geometry?</h3>
- They have 2 lone pairs and 3 bond pairings. Sp3D hybridization has been achieved in the core atom. The molecule is trigonally bipyramidal or T-shaped.
- At a 90° angle from the equatorial orbitals, two orbitals are placed along the vertical axis. The orbitals are trigonal bipyramidal in form. Lone pairs of electrons are present in two of the equatorial orbitals. The three atoms are positioned around the core atom to create a T-shaped molecule.
- T-shaped skills are a particular set of attributes that add value to an employee. A person with a T-shape has outstanding knowledge and skills in a certain field, and they excel at collaborating with others.

Answer:
824 g
Explanation:
First we <u>convert 7.0 x 10²⁴ formula units of magnesium chloride (MgCl₂) into moles</u>, using <em>Avogadro's number</em>:
- 7.0 x 10²⁴ formula units ÷ 6.023x10²³ formula units/mol = 11.62 mol MgCl₂
There are two Cl moles per MgCl₂ moles, meaning that we have (2 * 11.62) 23.24 moles of Cl
Finally we <u>convert 23.24 moles of chlorine into grams</u>, using <em>chlorine's molar mass</em>:
- 23.24 mol * 35.45 g/mol = 824 g
