The relationship between energy and wavelength is shown by:
E = hc/wavelength
As we can see, there is an inverse relation between energy and the wavelength. The greater the energy, the shorter the wavelength. Among the mechanical waves listed, at the wavelength of 7 cm.
The number of atoms in 92.6 mg of NH₄NO₂ is 8.714 x 10²³.
<h3>What are atoms?</h3>
Atoms are the basic unit of all matter. They join and form a matter. There may be similar or different types of atoms in one compound.
Given, the mass of NH₄NO₂ is 92.6 mg
The molar mass of NH₄NO₂ is 64.0 gm/mol
a. First, we calculate the number of moles:
moles of NH₄NO₂ = mass / molar mass
92.6 / 64.0 = 1.4468 mol
Number of moles of NH₄NO₂ is 1.4468 mol
b. Now to calculate the number of atoms:
Moles x Avogadro no. = 1.4468 x 6.023 x 10²³ = 8.714 x 10²³
Thus, the number of N atoms in 92.6 mg of NH₄NO₂ is 8.714 x 10²³

The overall reaction is:
Br₂(g) + 2 NO(g) ↔ 2 NOBr(g)
rate law = k [Br₂][NO]²
The first step of the overall reaction is:
NO(g) + Br₂(g) K₁⇄⇄K-1 NOBr₂(g)
rate law 1 = k₁ [Br₂][NO] or
rate law 2 = k-1 [NOBr₂]
The second step of the overall reaction is:
NOBr₂(g) + NO(g) →K₂→ 2 NOBr
rate law 3 = k₂[NOBr₂][NO]
So, rate law of overall reaction can be obtained as follows:
(rate law 1)*(rate law 3) / (rate law 2)
= [(k₁[Br₂][NO])* (K₂[NOBr₂][NO])] / k₋₁[NOBr₂]
= [k₁k₂/k₋₁][NO]²[Br₂]
So the correct answer is:
[k₁k₂/k₋₁][NO]² [Br₂]
