Explanation:
....![(K_{p})_{1}=5.3](https://tex.z-dn.net/?f=%28K_%7Bp%7D%29_%7B1%7D%3D5.3)
....![(K_{p})_{2}=2.1\times 10^{30}](https://tex.z-dn.net/?f=%28K_%7Bp%7D%29_%7B2%7D%3D2.1%5Ctimes%2010%5E%7B30%7D)
The given reaction can be written as summation of the following reaction-
![2NO+Br_{2}\rightleftharpoons 2NOBr](https://tex.z-dn.net/?f=2NO%2BBr_%7B2%7D%5Crightleftharpoons%202NOBr)
![N_{2}+O_{2}\rightleftharpoons 2NO](https://tex.z-dn.net/?f=N_%7B2%7D%2BO_%7B2%7D%5Crightleftharpoons%202NO)

![N_{2}+O_{2}+Br_{2}\rightleftharpoons 2NOBr](https://tex.z-dn.net/?f=N_%7B2%7D%2BO_%7B2%7D%2BBr_%7B2%7D%5Crightleftharpoons%202NOBr)
Equilibrium constant of this reaction is given as-
![\frac{[NOBr]^{2}}{[N_{2}][O_{2}][Br_{2}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BNOBr%5D%5E%7B2%7D%7D%7B%5BN_%7B2%7D%5D%5BO_%7B2%7D%5D%5BBr_%7B2%7D%5D%7D)

![=\frac{(5.3)^{2}}{2.1\times 10^{30}}=1.3\times 10^{-29}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%285.3%29%5E%7B2%7D%7D%7B2.1%5Ctimes%2010%5E%7B30%7D%7D%3D1.3%5Ctimes%2010%5E%7B-29%7D)
Answer:
The physical states that are represented by each graph region are the liquid and the solid, the highest temperature is the liquid and as it freezes it becomes a solid. The particles change because when it's a liquid, it isn't that compact it's just spreading smootly but as it freezes the atoms start to stick together and become compact.

Hope that made sense!
Answer:
pH = 12.2
Explanation:
Given data:
Mass of lime = 0.69 g
Volume = 1535 mL (1535 / 1000 = 1.535 L)
pH of solution = ?
Solution:
First of all we will determine the molarity.
Molarity = moles of solute / volume in litter
Number of moles = mass / molar mass
Number of moles = 0.69 g / 56.1 g/mol
Number of moles = 0.0123 mol
Molarity = moles of solute / volume in litter
Molarity = 0.0123 mol / 1.535 L
Molarity = 0.008 M
One mole of CaO neutralize two mole of OH⁻.
0.008 M×2 = 0.016 M
[OH⁻] = 0.016 M
pOH = -log [OH⁻]
pOH = [0.016]
pOH = 1.8
14 = pH +pOH
pH = 14 - pOH
pH = 14-1.8
pH = 12.2
Answer:
Because it is too dense for that to happen
Explanation:
It’s the second one, crest.
Crest is a section of wavelength.
