The order of the energy of the photons of given wave will be

= Ultraviolet waves > infrared waves > microwaves

$E = hv$

where,

E = energy of photon

$v$ = frequency of the radiation

h = Planck's constant = $6.63$ × $10$ ⁻³⁴ $J s$

We have :

(a) Frequency of infrared waves = $v$ ₁ = $6.5$ × $10$ ¹³ $J s$

(b) Frequency of microwaves= $v$ ₂ = $9.8$ × $10$ ¹¹ $J s$

So, the decreasing order of the frequencies of the waves will be :

$v$ ₃ $>$ $v$ ₁ $> v$ ₂

As we can see from the formula that energy is directly proportional to the frequency of the wave.

$E$ ∝ $v$

So, the order of the energy of the photons of given wave will be same as their order of frequencies:

$E$ ₃> $E$ ₁ > $E$ ₂

= Ultraviolet waves > infrared waves > microwaves

Also the complete question is :

Rank the following photons in terms of decreasing energy:

(a) IR (v = 6.5 x 10¹³ s⁻¹)

(b) microwave (v = 9.8 x 10¹¹ s⁻¹)

Nitrogen dioxide is a red-brown gas responsible for the brown color of smog. A container of nitrogen dioxide that is at low pres

____ [38]

Answer:

Initially $1.51\times 10^{-2} moles$ of nitrogen dioxide were in the container .

Explanation:

Volume of the container at low pressure and at room temperature = $V_1=3.4 L$

Number of moles in the container = $n_1$

After more addition of nitrogen gas at the same pressure and temperature.

Volume of the container after addition = $V_2=5.11 L$

Number of moles in the container after addition= $n_2=2.28\times 10^{-2} mol$

Applying Avogadro's law:

$\frac{Volume}{Moles}=constant$ (at constant pressure and temperature)

$\frac{V_1}{n_1}=\frac{V_2}{n_2}$

$n_1=\frac{V_1\times n_2}{V_2}=\frac{3.4 L\times 2.28\times 10^{-2} mol}{5.11 L}$

$n_1=1.51\times 10^{-2} mol$

Initially $1.51\times 10^{-2} moles$ of nitrogen dioxide were in the container .

Write Qc for each of the following:(1) Gaseous sulfur tetrafluoride reacts with liquid water to produce gaseous sulfur dioxide a

snow_tiger [21]

Answer : The expression for reaction quotient will be :

(1) $Q_c=\frac{[SO_2][HF]^4}{[SF_4]}$

(2) $Q_c=\frac{[O_2]^2[Xe]}{[XeF_2]}$

Explanation :

Reaction quotient $(Q_c)$ : It is defined as the measurement of the relative amounts of products and reactants present during a reaction at a particular time.

(1) The given balanced chemical reaction is,

$SF_4(g)+2H_2O(l)\rightarrow SO_2(g)+4HF(g)$

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted. So, the expression for reaction quotient will be :

$Q_c=\frac{[SO_2][HF]^4}{[SF_4]}$

(2) The given balanced chemical reaction is,

$2MoO_2(s)+XeF_2(g)\rightarrow 2MoF(l)+Xe(g)+2O_2(g)[/texIn this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted. So, the expression for reaction quotient will be :[tex]Q_c=\frac{[O_2]^2[Xe]}{[XeF_2]}$
