Explanation:
Given that,
The frequency of electromagnetic spectrum is ![2.73\times 10^{16}\ Hz](https://tex.z-dn.net/?f=2.73%5Ctimes%2010%5E%7B16%7D%5C%20Hz)
(A) Let the wavelength of this radiation is
. We know that,
![c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{2.73\times 10^{16}}\\\\\lambda=1.09\times 10^{-8}\ m](https://tex.z-dn.net/?f=c%3Df%5Clambda%5C%5C%5C%5C%5Clambda%3D%5Cdfrac%7Bc%7D%7Bf%7D%5C%5C%5C%5C%5Clambda%3D%5Cdfrac%7B3%5Ctimes%2010%5E8%7D%7B2.73%5Ctimes%2010%5E%7B16%7D%7D%5C%5C%5C%5C%5Clambda%3D1.09%5Ctimes%2010%5E%7B-8%7D%5C%20m)
So, the wavelength of this radiation is
.
(B) Let E is the energy associated with this radiation. Energy of an electromagnetic radiation is given by :
![E=hf](https://tex.z-dn.net/?f=E%3Dhf)
h is Planck's constant
![E=6.63\times 10^{-34}\times 2.73\times 10^{16}\\\\E=1.8\times 10^{-17}\ J](https://tex.z-dn.net/?f=E%3D6.63%5Ctimes%2010%5E%7B-34%7D%5Ctimes%202.73%5Ctimes%2010%5E%7B16%7D%5C%5C%5C%5CE%3D1.8%5Ctimes%2010%5E%7B-17%7D%5C%20J)
1 kcal = 4184 J
It means,
![1.8\times 10^{-17}\ J=\dfrac{1}{4184}\times 1.8\times 10^{-17}\\\\=4.3\times 10^{-21}\ \text{kcal}](https://tex.z-dn.net/?f=1.8%5Ctimes%2010%5E%7B-17%7D%5C%20J%3D%5Cdfrac%7B1%7D%7B4184%7D%5Ctimes%201.8%5Ctimes%2010%5E%7B-17%7D%5C%5C%5C%5C%3D4.3%5Ctimes%2010%5E%7B-21%7D%5C%20%5Ctext%7Bkcal%7D)
Hence, this is the required solution.
Well it matters If it touch with liquid or soild, if touched with liquid it is not call wet, but with soild yes because something dry will get went when touched with water but something wet will stay wet when touched with water.
Following reaction arise between Br2 and Cl2
Br2 + Cl2 → 2BrCl
(1mole) (1mole) (2moles)
From above balanced reaction, it can be seen that 1 mole of Br2 reacts with 1 mole of Cl2 to form 2 mole of BrCl
Thus, when <span>2.74 mol Cl2 reacts with excess Br2, 2.74 X 2 = 5.48 moles of BrCl will be formed. </span>
Answer:
Both liquids and gases are fluids = true
The answer is intermediate, so E.
