Answer:pressure A<B
RMS speed A<B
Average kinetic energy A<B
Explanation:
All three listed properties of the gases depend on molecular weight. The lighter the gas, the more it's pressure, root mean square speed and average kinetic energy. If a gas has a high relative molecular weight, it have a high velocity as predicted by Graham's law. Hence the answer.
Blow a lot of air into it you can stick an air pump and when your done pumping quickly put tape over the hole
Answer:
Partial pressure of Br2 = 0.01158 atm
Partial pressure of I2 = 0.00158 atm
Partial pressure of IBr =0.07684 atm
Explanation:
Step 1: Data given
Temperature = 350 K
K = 322
Initial partial pressure of bromine = 0.0500 atm
Initial partial pressure of iodine = 0.0400 atm
Step 2: The balanced equation
Br2(g) + I2 ⇆ 2IBr(g)
Step 3: The initial pressures
pBr2 = 0.0500 atm
pI2 = 0.0400 atm
pIBr = 0 atm
Step 3: The pressure ate the equilibrium
pBr2 = 0.0500 - X atm
pI2 = 0.0400 -X atm
pIBr = 2X atm
Step 4: Define K
K = (pIBr)² / (pBr2)*(pI2)
Step 5: Calculate X
322 = (2X)² / (0.0500-X)(0.0400-X)
X = 0.03842
pBr2 = 0.0500 - 0.03842 = 0.01158 atm
pI2 = 0.0400 -0.03842 = 0.00158 atm
pIBr = 2*0.03842 = 0.07684 atm
Explanation:
Greenhouse gases are gases in Earth's atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere.
B. 347 m/s
My friend and I did an experiment to find the speed of sound and we came very close to the actual value.
