A mixture of He, Ar and Xe has a total pressure of 2.00 atm. The partial pressure of He is .450 atm, Ar partial pressure is 0.400. What is the partial pressure of Xe?

P(Xe) = 1.15 atm

Explanation:

Given data:

Total pressure = 2.00 atm

Partial pressure of He = 0.450 atm

Partial pressure of Ar  = 0.400 atm

Partial pressure of Xe = ?

Solution:

According to Dalton law of partial pressure,

The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.

Mathematical expression:

P(total) = P₁ + P₂ + P₃+ +Pₙ

Now we will solve this  problem by using this law.

P(total) = P(He) + P(Ar) + P(Xe)

2.00 atm = 0.450 atm + 0.400 atm + P(Xe)

2.00 atm = 0.850 atm + P(Xe)

P(Xe) = 2.00 atm - 0.850 atm

P(Xe) = 1.15 atm

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
