Answer:
V = 34.55 L
Explanation:
Given that,
No of moles, n = 1.4
Temperature, T = 20°C = 20 + 273 = 293 K
Pressure, P = 0.974 atm
We need to find the volume of the gas. It can be calculated using Ideal gas equation which is :
PV=nRT
R is gas constant, ![R=0.08206\ L-atm/mol-K](https://tex.z-dn.net/?f=R%3D0.08206%5C%20L-atm%2Fmol-K)
Finding for V,
![V=\dfrac{nRT}{P}\\\\V=\dfrac{1.4\times 0.08206\times 293}{0.974 }\\\\V=34.55\ L](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7BnRT%7D%7BP%7D%5C%5C%5C%5CV%3D%5Cdfrac%7B1.4%5Ctimes%200.08206%5Ctimes%20293%7D%7B0.974%20%7D%5C%5C%5C%5CV%3D34.55%5C%20L)
So, the volume of the gas is 34.55 L.
Hydrogen fuses into helium
Answer:
yes, the number of protons makes an atom whatever element it is, and the number of protons cannot be changed, because changing the number of protons would change what element it is. the number of protons in each element is unique.
Explanation:
Answer:
Likely an issue with the mitral valve.
Explanation:
If I read this correctly, you are likely referring to mitral regurgitation, which is a process where your mitral value does not close tightly enough to stop the blood to flow into left atrium.
Normally, when the left ventricle is full, the mitral valve shuts to prevent blood blood from flowing backward into the atrium while the ventricle contracts, and this allows for blood to go to aorta and to body. According to question since the process is reversed, I am gonna go out on a limb and say mitral valve is likely the structure affected by this since and how I came to conclusion is all the explaintion I did earlier.
