The more kinetic energy a substance has, the warmer it will be and the faster particles will be moving, which reduces the density of the substance
Given:
Q = 9.4 kJ/(kg-h), the heat production rate
c = 4.18 J/(g-K), the heat capacity
t = 2.5 h, amount of time
Note that
c = 4.18 J/(g-K) = 4180 J/(kg-K) = 4.18 kJ/kg-K)
Consider 1 kg of mass.
Then
Qt = cΔT
where ΔT is the increase in temperature (°K)
(1 kg)*(9.4 kJ/(kg-h))*(2.5 h) = (1 kg)*(4.18 kJ/(kg-K))*(ΔT K)
23.5 = 4.18 ΔT
ΔT = 23.5/4.18 = 5.622 K = 5.622 °C
Answer: 5.62 K (or 5.62 °C)
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:
27.08 x 10²³ atoms of Al .
Explanation:
121.4 grams of Aluminum = 121.4 / 26.98 moles of Aluminum
= 4.4996 moles
1 mole of Aluminum contains 6.02 x 10²³ atoms of Al
4.4996 moles of Aluminum contains 6.02 x 10²³ x 4.4996 atoms of Al
= 27.08 x 10²³ atoms .
