The vapor pressure of water and the partial pressure of hydrogen contribute to the total pressure of 715 torr. What is the parti
Lostsunrise [7]

Answer:

0.91 atm is the partial pressure of just hydrogen gas.

Explanation:

Vapor pressure of water , p= 0.0313 atm

Partial pressure of hydrogen gas = p_{H_2}

Total pressure of the water vapors and hydrogen gas = P = 715 Torr

1 atm = 715 Torr

715 Torr=\frac{715}{760} atm=0.94 atm

According Dalton's law of partial pressure:

P=p+p_{H_2}

0.94 atm=0.0313 atm+p_{H_2}

p_{H_2}=0.94 atm - 0.0313 atm =0.9087 atm \approx 0.91 atm

0.91 atm is the partial pressure of just hydrogen gas.

A chunk of ice breaks off a glacier and falls 30.0 m before it hits the water. Assuming it falls freely (there is no air resista
lina2011 [118]

Answer:

The ice chunk will take 2.47 seconds to hit the water.

Explanation:

Height from which ice chunk fell = h = 30.0 m

Initial velocity of the ice chunk = u = 0 m/s

Time taken by ice chunk to cover 30.0 m of height = t

Acceleration due to gravity = g 9.8m/s^2

Using second equation of motion ;

h=ut+\frac{1}{2}gt^2

30.0 m=0 m/s\times t+\frac{1}{2}\times 9.8 m/s^2\times t^2

t=\sqrt{\frac{30.0m/s\times 2}{9.8 m/s^2}}2.47 s

The ice chunk will take 2.47 seconds to hit the water.
