Answer:
6 different frequencies
Explanation:
From energy level 1 to 2 is one frequency, from energy level 1 to 3 is one frequency and From energy level 1 to 4 is one frequency. So, we have a total of 3 frequencies for transition from energy level 1.
From energy level 2 to 3 is one frequency and from energy level 2 to 4 is one frequency. So, we have a total of 2 frequencies for transition from energy level 2.
From energy level 3 to 4 is one frequency.
So we have a total of 3 + 2 + 1 different frequencies = 6 different frequencies.
Note that the reverse process for each step produces the same frequency as the step in consideration.

<u>Answer:</u> The rate law of the reaction is ![\text{Rate}=k[HgCl_2][C_2O_4^{2-}]^2](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BHgCl_2%5D%5BC_2O_4%5E%7B2-%7D%5D%5E2)
<u>Explanation:</u>
Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
For the given chemical equation:
![2 HgCl_2(aq.)+C_2O_4^{2-}(aq.)\rightarrow 2Cl^-(aq.)+2CO_2(g)+Hg_2Cl_2(s)](https://tex.z-dn.net/?f=2%20HgCl_2%28aq.%29%2BC_2O_4%5E%7B2-%7D%28aq.%29%5Crightarrow%202Cl%5E-%28aq.%29%2B2CO_2%28g%29%2BHg_2Cl_2%28s%29)
Rate law expression for the reaction:
![\text{Rate}=k[HgCl_2]^a[C_2O_4^{2-}]^b](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BHgCl_2%5D%5Ea%5BC_2O_4%5E%7B2-%7D%5D%5Eb)
where,
a = order with respect to ![HgCl_2](https://tex.z-dn.net/?f=HgCl_2)
b = order with respect to ![C_2O_4^{2-}](https://tex.z-dn.net/?f=C_2O_4%5E%7B2-%7D)

Dividing 2 from 1, we get:
![\frac{2.9\times 10^{-4}}{3.2\times 10^{-5}}=\frac{(0.164)^a(0.45)^b}{(0.164)^a(0.15)^b}\\\\9=3^b\\b=2](https://tex.z-dn.net/?f=%5Cfrac%7B2.9%5Ctimes%2010%5E%7B-4%7D%7D%7B3.2%5Ctimes%2010%5E%7B-5%7D%7D%3D%5Cfrac%7B%280.164%29%5Ea%280.45%29%5Eb%7D%7B%280.164%29%5Ea%280.15%29%5Eb%7D%5C%5C%5C%5C9%3D3%5Eb%5C%5Cb%3D2)
Dividing 2 from 3, we get:
![\frac{2.9\times 10^{-4}}{1.4\times 10^{-4}}=\frac{(0.164)^a(0.45)^b}{(0.082)^a(0.45)^b}\\\\2=2^a\\a=1](https://tex.z-dn.net/?f=%5Cfrac%7B2.9%5Ctimes%2010%5E%7B-4%7D%7D%7B1.4%5Ctimes%2010%5E%7B-4%7D%7D%3D%5Cfrac%7B%280.164%29%5Ea%280.45%29%5Eb%7D%7B%280.082%29%5Ea%280.45%29%5Eb%7D%5C%5C%5C%5C2%3D2%5Ea%5C%5Ca%3D1)
Thus, the rate law becomes:
![\text{Rate}=k[HgCl_2]^1[C_2O_4^{2-}]^2](https://tex.z-dn.net/?f=%5Ctext%7BRate%7D%3Dk%5BHgCl_2%5D%5E1%5BC_2O_4%5E%7B2-%7D%5D%5E2)

<h3>What is
Homogenization?</h3>
Any of a number of methods, including homogenization and homogenisation, are used to uniformly combine two liquids that are insoluble in one another. To do this, one of the liquids is changed into a state in which very minute particles are evenly dispersed across the other liquid. The process of homogenizing milk, in which the milk fat globules are equally distributed throughout the remaining milk and reduced in size, is a classic example. In order to create an emulsion, two immiscible liquids (i.e., liquids that are not soluble in all amounts one in another) must be homogenized (from "homogeneous"; Greek, homos, same + genos, kind)[2] (Mixture of two or more liquids that are generally immiscible).
