Dalton's Law of Partial pressure: The total pressure of a gas mixture is the sum of the partial pressures of each gas . Therefore if I have a gas chamber with 3.1 atm of Xe and 0.8 atm of N2 and no H2,.. What is the pressure in the chamber.

The total pressure of this gas mixture in the chamber is 3.9 atm

Explanation:

Step 1: Data given

Partial pressure of Xe = 3.1 atm

Partial pressure of N2 = 0.8 atm

Partial pressure of H2= 0 atm

Dalton's law says: Total pressure of a gas mixture = sum of partial pressure of gasses

Step 2: Calculate the total pressure of a gas mixture

Dalton's law says: Total pressure of a gas mixture = sum of partial pressure of gasses

Total pressure of the gas mixture = Partial pressure of Xe + Partial pressure of N2 + partial pressure of H2

Total pressure of the gas mixture = 3.1 atm + 0.8 atm + 0 atm

Total pressure of the gas mixture =  3.9 atm

The total pressure of this gas mixture in the chamber is 3.9 atm

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

if you're asking what comes out, it's steam.
