what is stastical thermodaynamics deal?
Explanation:
Statistical thermodynamics is a theory that uses molecular properties to predict the behavior of macroscopic quantities of compounds. ... From these energy-level data, a temperature-dependent quantity called the partition function can be calculated.
Answer:
the stastical thermodaynamics deal is essentially a theory that you can use the molecules and their properties in order to predict how the molecule will behave in a macroscopic quantities of compounds. Using this, you can also tell a temperature-dependent quantity called the partition function.

What is 797 mm hg to atm?
Answer:
797 mm hg = 1.04868 atm
Explanation:
1 atm = 760 mm hg
797 mm hg to atm is 1.0468 atm
Pressure is defined as the physical force exerted on an object. The force applied is perpendicular to the surface of objects per unit area.
There are many different types of units and prefixes that may be used in general practice to reflect pressure. Thus, it is ensured that all the measurements and their respective units are in the same framework when conducting pressure calculations.
Pascal is the SI unit of pressure, and is the basic pressure unit in the SI (the International System of Units) system.
Given,
Pressure = 797 atm
1 mm Hg = 0.00131579 atm
797 mm Hg = 0.00131579 × 797
= 1.04868 atm

how dose dissolving sugar in water show that matter is made up of particles
Answer:
When sugar dissolves, the sugar particles separate from each other and mix with the water particles. When the sugar particles separate, the smaller water particles fit into the spaces between the larger sugar particles. The water and sugar particles are attracted to each other, so they move closer together when they mix.

what is the dilution factor if you add a 0.1ml aliquot of a specimen to 9.9 dilutent
The dilution factor : 100
Further explanationThe dilution factor(DF) : ratio of concentration of stock solution and diluted solution or ratio of the volume of final solution to the initial volume from stock solution
From equation of dilution :
M₁V₁=M₂V₂
[tex]\tt DF=\dfrac{M_1}{M_2}=\dfrac{V_2}{V_1}[/tex]
Volume of aliquot = 0.1 ml
Volume of diluent = 9.9 ml
So final volume :
[tex]\tt V_f(final~volume)=volume~aliquot+volume~diluent\\\\V_f=0.1+9.9=10~ml[/tex]
The dilution factor (DF) :
[tex]\tt D_f=\dfrac{V_f}{V_i}\\\\D_f=\dfrac{10}{0.1}=100[/tex]
Your skin is an important organ and has several functions. All of the functions below are performed by the skin EXCEPT
A)
makes vitamin D.
B
prevents-dehydration:
C)
maintains body temperature.
D)
works with bones to help you move.
Answer:D
Explanation:
Your skin makes vitamin D
Your skin prevents dehydration
And your skin maintains body temperature. So you are left with D
Answer:
The correct option is D.
works with bones to help you move
Explanation:
Skin is the outer layer of the body and it is the body's largest organ.
It protect the body from heat and other harmful substances.
It is comprises of three layers;
The Epidermis which is the outer layer.
The dermis which is a fibrous later that protect the Epidermis.
The subcutis is the subcutaneous layer that is beneath the dermis.
Function of the skin.
1. It's regulate body temperature
2. It's protect the body from heat and pathogenic entry.
3. It produces vitamin D
4. The skin allow sensations or feelings of touch, heat, and cold.
Therefore;
works with bones to help you move is wrong because it is the muscle that work with the bone.

A. 4-fluorobutane
B. 2-fluorobutane
C. 1-fluorobutane
D. 1-fluoropentane
Answer:
The correct answer is (C)
Which is "1-fluorobutane"
Explanation:
Hope this helped if so please leave a "Rating" and "Like" and MARK me Brainliest if it was the BEST answer! THANKS! :)
The name of the hydrocarbon CH3CH2CH2CH2F is 1-fluorobutane.
In naming organic hydrocarbons, we count the number of the parent chain family. Here, we have an alkane with 4 carbons, which means that the parent chain is a family of alkane. The fourth compound in the family of an alkane is butane.
Afterwards, we will determine if there is any substituent attached to any of the carbon atoms in the chain and rank them in a way such that we have the lowest possible number.
Here, the fluorine is attached to the first carbon atom. So, it becomes 1-fluorobutane.

Molecular orbital diagram for Fe.
ANSWER;
1s22s22p63s23p63d64s2
EXPLANATION;
Molecular orbital diagram for Fe.
In writing the electron configuration for Iron the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Iron go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the next six electrons. We now shift to the 4s orbital where we place the remaining two electrons. After the 4s is full we put the remaining six electrons in the 3d orbital and end with 3d6.
Therefore the Iron electron configuration will be 1s22s22p63s23p64s23d6.
Note that when writing the electron configuration for an atom like Fe, the 3d is usually written before the 4s. Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written
Therefore we have 1s22s22p63s23p63d64s2

what does the phrase sea of electrons describe?? please help
Answer: Metallic Bonding.In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.
