Answer: The partial pressure of oxygen is 76.56 atm , partial pressure of carbon dioxide is 10.44 atm and the total pressure is 87 atm.
Explanation:
According to the ideal gas equation:'
P = Pressure of the gas = ?
V= Volume of the gas =
T= Temperature of the gas = 10°C = 373 K
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas= 0.25 +0.034 = 0.284 moles
= mole fraction of oxygen=
,
=mole fraction of carbon dioxide=
partial pressure of oxygen =
partial pressure of carbon dioxide=
The partial pressure of oxygen is 76.56 atm , partial pressure of carbon dioxide is 10.44 atm and the total pressure is 87 atm.
Answer:
275.3 nm is the wavelength of light required for mercury.
Mercury can not be used to generate electricity from the sun because wavelength at which mercury will emit an electron is smaller than 500 nm.
Explanation:
The wavelength of light required for mercury to emit an electron.
The wavelength of the radiation =
Energy required fro mercury to to emit an electron = E
Energy required fro mercury to to emit an electron will the energy if the radiation = E' =
E' = E
To calculate the wavelength of light, we use the equation:
where,
= wavelength of the light
h = Planck's constant =
c = speed of light =
Wavelength of the sun light in the visible region = 500 nm
500 nm > 275.3 nm
Less energy < more energy
So, this means that mercury can not be used to generate electricity from the sun.
