At a temperature of 30 deg C, the vapour pressure of water
H2O is about 32 mm Hg. Therefore at a total pressure f 734 mm Hg, the partial
pressure of the Hydrogen gas collected is:
<span>P Hydrogen = 734 mm Hg – 32 mm Hg = 702 mm Hg</span>
Answer: The final pressure will decrease ad the value is 85 kPa
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,

where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:

Putting values in above equation, we get:

Hence, the final pressure will decrease ad the value is 85 kPa
Answer:Artificial light from cities has created a permanent "skyglow" at night, obscuring our view of the stars. Here's their map of artificial sky brightness in North America, represented as a ratio of "natural" nighttime sky brightness. In the black areas, the natural night sky is still (mostly) visible.
Explanation:
Particles are farther apart in gases so substance X is water vapor
Explanation:
The best statement that fits the two described substances is that particles are farther apart in gases so substance X is water vapor. For a give mass of substance, gases occupies more volume.
Gases do not have specific volumes, occupy space randomly and fills whichever container they are found in.
Liquids on the other hand like solids have specific volume because their particles are very close together.
Particles of gases are random and their molecules are far apart.
