Diffusion is the movement of a solute from an area of its high concentration to an area of its low concentration – i.e. down a concentration gradient. This process is “passive” – i.e. it requires no energy; the gradient is enough to drive the process.

What rules should you follow when multiplying and dividing? Check all that apply.
xeze [42]

Answer:

exponents

Explanation:

The exponents in scientific notation should be added when multiplying, and subtracted when dividing. The exponents need to be the same so the leading numbers can be multiplied or divided. The result has the same number of decimal places as the least precise number.

Suppose that 5-ml containers of helium (He), neon (Ne), and argon (Ar) are at pressures of 1 atm,
Katarina [22]

The total pressure in the container after the three gases are mixed is 6 atm and the partial pressure of He is 1 atm.

<h3>What is Dalton's Law of Partial Pressure ?</h3>

According to Dalton's Law of Partial Pressure , the pressure exerted by a mixture of gas is equal to the sum of the partial pressure of the gases in the mixture.

P(total) = p₁ +p₂+p₃+.....

As the volume of the containers are same and the

n = 1*5/RT for Helium

n = 2*5 /RT for Neon

n= 3*5/RT for Argon

Mole fraction = moles of the element/Total moles

Moles fraction of Helium is

\rm \dfrac{1*5}{1*5+2*5+3*5}

= 1/6

Total Pressure in the container = 1 + 2 +3 = 6 atm

The partial pressure of Helium will be

=Mole fraction * Total pressure

=(1/6)*6 atm

= 1 atm , as the volume is same the temperature is same , the pressure will also be same.
