a flask contains a gas mixture of hydrogen and nitrogen. the total pressure of the mix is 2.0 atm. the partial pressure of the hydrogen is 0.8 atm. what is the partial pressure of the nitrogen?

a. 0.8 atm
b. 1.2 atm
c. 2.0 atm
d. 2.8 atm

The correct answer is option B.

Explanation:

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gases.

Where :

= total pressure

= partial pressure of nitrogen gas  

= partial pressure of hydrogen gas

= partial pressure of nth gas

We have:

P = 2.0 atm,

Using Dalton's law of partial pressure:

1.2 atm is the partial pressure of the nitrogen.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
