Answer: 0.055 moles of are produced by the reaction of 0.055 mol of ammonium perchlorate.
Explanation:
The balanced chemical reaction for decomposition of ammonium perchlorate is:
According to stoichiometry :
2 moles of produce = 2 moles of
Thus 0.055 moles of will produce =
of
Thus 0.055 moles of are produced by the reaction of 0.055mol of ammonium perchlorate.
Answer :
(1) The frequency of photon is,
(2) The energy of a single photon of this radiation is
(3) The energy of an Avogadro's number of photons of this radiation is, 11.97 J/mol
Explanation : Given,
Wavelength of photon = (1 m = 100 cm)
(1) Now we have to calculate the frequency of photon.
Formula used :
where,
= frequency of photon
= wavelength of photon
c = speed of light =
Now put all the given values in the above formula, we get:
The frequency of photon is,
(2) Now we have to calculate the energy of photon.
Formula used :
where,
= frequency of photon
h = Planck's constant =
Now put all the given values in the above formula, we get:
The energy of a single photon of this radiation is
(3) Now we have to calculate the energy in J/mol.
The energy of an Avogadro's number of photons of this radiation is, 11.97 J/mol
