A mixture of He, Ne, and N2 gases are a pressure of 1.348. If the pressures of He and Ne are 0.124 atm, what is the partial pressure of N2 in the mixture ?
Answers
Answer : The partial pressure of in the mixture is, 1.224 atm
Solution :
According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.
where,
= total partial pressure of
= 1.348 atm
= partial pressure of helium
= partial pressure of neon
= partial pressure of nitrogen
As we are given that,
Now put all the given values in above expression, we get the partial pressure of the nitrogen gas in the mixture.
Therefore, the partial pressure of in the mixture is, 66 Kpa
The Best Answer: 1 - (.47+.23) = 0.30
If Ne has a mole fraction of 0.47 (or 47/100) and Ar is 0.23, then H2(or He) has a mole fraction of 0.30
This means the gas mixture is 30/100 H2(or He).
7.85 x 0.30 = 2.355 atm

Proteins catalyze reactions, part of the immune system, transport molecules such as oxygen, and transmit messages from cell to cell.
What is protein?
Proteins are very large molecules made of basic units known as aminoacids. Proteins consist of carbon (C), hydrogen (H), nitrogen (N), oxygen (O), and sulfur (S).
Protein molecules are produced by twisted and folded strands of amino acids. Proteins are actively involved in the most important as well as basic aspects of life. These include metabolism, cellular communication, movement, molecular recognition, and defense.
The shape of structural proteins allows them to form essential structures of the body. Collagen holds most of the body tissues together, a protein with a fiber shape. Structural protein Keratin creates a network of waterproof fibers on the outer layer of the skin.
The shape of functional proteins enables them to contribute to the chemical processes of the body. Functional proteins include cell membrane receptors, hormones, growth factors, and enzymes.

Answer:
A. .2 M/s2
Explanation:
Force = mass x acceleration
The force is given as 20 N and tthe mass as 100kg
Solve for accelartion as 20/100 = .2
(Also wrong subject this is a Physics problem)
Answer:
The answer is 0.2m/s^2
Explanation:
As we all know that, Force=Mass* Acceleration
So, to make acceleration the subject of the formular, we have Acceleration=Force/mass
And we were given that, Force=20N
Mass=100kg
So, Acceleration= 20/100
=0.2m/s^2
