Answer:
Partial pressure of in the gas was 733 torr and mass of
in the sample was 2.12 g.
Explanation:
a) Total pressure of gas = (partial pressure of water vapour)+(partial pressure of )
Here partial pressure of water vapour is 21 torr and total pressure of gas is 754 torr.
So, partial pressure of = (total pressure of gas)-(partial pressure of water vapour) = (754 torr) - (21 torr) = 733 torr
b) Lets assume that behaves ideally. Hence-
PV=nRT
where P is pressure of , V is volume of
, n is number of moles of
, R is gas constant and T is temperature in kelvin
here P = 733 torr = = 0.9646 atm
V = 0.65 L, R = 0.082 L.atm/(mol.K), T=(273+22)K = 295 K
So,
=
= 0.0259 moles
As 3 moles of are produced from 2 moles of
therefore 0.0259 moles of
are produced from
moles or 0.0173 moles of
.
Molar mass of = 122.55 g
So mass of in sample =
= 2.12 g
It is a radio wave
Explanation:
The energy of an electromagnetic waves is related to its frequency by the equation:
where
h is the Planck constant
f is the frequency of the wave
We notice that the energy of an electromagnetic wave is proportional to its frequency. This means that waves with higher frequencies, such as gamma rays, x-rays, are more energetic, while waves with lower frequencies, such as microwave and radio waves, are the less energetic.
In this case, we want to find the frequency of a wave with energy
E = 0.000001 eV
Converting into Joules,
Solving for the frequency,
Which falls in the range of frequency of radio waves.
