An apparatus consists of a 4.0 dm3 flask containing nitrogen gas at 25 oc and 803 kpa. it is joined by a valve to a 10.0 dm3 flask containing argon gas 25 oc and 47.2 kpa. the valve is opened and the gases mix. i. what is the partial pressure of each gas after mixing?

Partial pressure of nitrogen = 229.43 kpa

Partial pressure of argon = 33.7 Kpa

Explanation:

Given data:

Volume of flask one = 4.0 dm³

Temperature = 25°C

Pressure of nitrogen = 803 KPa

Final volume = 4.0 dm³ + 10.0 dm³ =  14.0 dm³

Initial volume of argon = 47.2 KPa

Final pressure of both gases when valve is open = ?

Solution:

For nitrogen:

P₁V₁ = P₂V₂

803 KPa × 4 dm³ = P₂ × 14.0 dm³

P₂ = 803 KPa × 4 dm³ /  14.0 dm³

P₂ = 3212 kpa / 14.0

P₂ = 229.43 kpa

For argon:

P₁V₁ = P₂V₂

47.2 KPa × 10.0 dm³  = P₂× 14.0 dm³

P₂ = 47.2 KPa × 10.0 dm³/14.0 dm³

P₂ = 472 kpa/ 14.0

P₂ = 33.7 Kpa

the answer is learned

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
