Answer: The initial partial pressures of and is 139.4 torr.
Explanation:
The equilibrium reaction is
initially conc. p p 0
At eqm. p-2x p-x 2x
Given:
The expression for equilibrium constant is :
= 2x =115 torr
= (p-2x) = p-115 torr
= (p-x)= p-57.5 torr
Now put all the given values in this expression, we get
Therefore, the initial partial pressures of and is 139.4 torr.
Answer:
B) it reacts with sodium metal to form sodium hydroxide and hydrogen gas
Explanation:
B is the only option that show a chemical property, density, freezing, and boiling points are physical properties.
Answer:
2.04 atm
Explanation:
The pressure of the gas can be found by using the equation of state for an ideal gas:
where
p is the gas pressure
V is the gas volume
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
For this gas we have:
n = 0.316 mol (moles)
V = 4.00 L (volume)
T = 315 K (absolute temperature)
(gas constant)
Therefore, the gas pressure is
In the blank there will be WAVELENGTH.
In a longitudinal wave, the WAVELENGTH is the distance from one compression to the next compression or from one rarefaction to the next rarefaction.
