mash [69]

Answer:

Yep. Many of the sounds we associate with white noise are actually pink noise, or brown, or green, or blue. In audio engineering, there's a whole rainbow of noise colors, each with its own unique properties, that are used to produce music, help relaxation, and describe natural rhythms like the human heartbeat.

A mixture of 1.20 mols He, 2.40 mols Ne, 4.80 mols Kr, and 0.60 mols Ar has a total pressure of 600.0 mm Hg. What is the partial
Juliette [100K]

Answer: The partial pressure of the Kr is 320 mm Hg.

Explanation:

According to Raoult's Law , the partial pressure of each component in the solution is equal to the total pressure multiplied by its mole fraction. It is mathematically expressed as

p_A=x_A\times P_{total}

where, p_A = partial pressure of component A

x_A = mole fraction of A

P_{total} = total pressure

mole fraction of Krypton = \frac{\text {Moles of Kr}}{\text {total moles}}=\frac{4.80}{1.20+2.40+4.80+0.60}=0.53

p_{Kr}=0.53\times 600mmHg=320mmHg

Thus partial pressure of the Kr is 320 mm Hg

What three tests must all theories pass to be considered a "proven" theory?
VladimirAG [237]

 In order to become a scientific theory the three categories that it must pass are the following: 


1) Can the phenomena be recreated in a laboratory setting? 


2) Can variables be changed, yet still result in like observations? 


3) Is the phenomena truly natural or was it the result of a man-made force enacting upon it?
