andrezito [222]

Answer

Susan can process wind speed data from different regions.

Explanation

A Doppler radar is used in weather forecasting in measuring the direction and speed of objects such as drops of precipitation. It determines if the movement occurring in the atmosphere is horizontally towards or way from the radar. Susan can obtain velocity data about objects at a distance which might be water droplets thus be able to predict a coming weather

a sample of H2 is collected over water such that the combined hydrogen water vapor sample is held at a pressure of one standard
Trava [24]

Answer : The partial pressure of H_2 is 98.825 kPa.

Solution : Given,

Total pressure of hydrogen water vapor = 1 atm = 101.325 kPa    (1 atm = 101.325 kPa)

Partial pressure of water vapor = 2.5 kPa

Dalton's law of partial pressure : It is defined as the total pressure exerted is equal to the sum of the partial pressure of individual gases.

Formula used :

P_{Total}=\sum_{i=1}^nP_i

P_{Total} = Total pressure

P_{i} = Partial pressure of individual gases

P_{Total}=P_{H_2}+P_{\text{ Water vapor}}

Now put all the given values in this expression, we get

101.325kPa=P_{H_2}+2.5kPa

P_{H_2}=98.825kPa

Therefore, the partial pressure of H_2 is 98.825 kPa.
