Answer:

Frequency=1.6\times 10^{12}\ Hz

Explanation:

The relation between frequency and wavelength is shown below as:

c=frequency\times Wavelength


c is the speed of light having value 3\times 10^8\ m/s

Given, Wavelength = 188 μm

Also, 1 μm = 10^{-6} nm

So,  

Wavelength = 188\times 10^{-6} m

Thus, Frequency is:

Frequency=\frac{c}{Wavelength}

Frequency=\frac{3\times 10^8}{188\times 10^{-6}}\ Hz

Frequency=1.6\times 10^{12}\ Hz

Which linkages in starch and triglycerides result from condensation reactions? glycosidic bonds in starch and ester bonds in tri
bogdanovich [222]
Glycosidic bonds in starch and ester bonds in triglycerides. The glycosidic bond is considered to be the covalent synthetic bonds that connection ring-molded sugar particles to different atoms. The frame by a buildup response between a liquor or amine of one particle and the anomeric carbon of the sugar, and hence, might be O-connected or N-connected.

Salicylamide can undergo an iodination by electrophilic aromatic substitution. Arrange the procedural steps in order to iodinate
Tanzania [10]

The procedural steps in order to get iodinate salicylamide are as follows:

  • It begins first at a laboratory.
  • Secondly, one has to dissolve salicylamide in ethanol.
  • Then one has to add sodium iodide.
  • Later on, one has to add sodium hypochlorite to the ice cold solution of salicylamide and sodium iodide.
  • Thereafter one has to sodium thiosulfate.
  • It is better to Acidify by a person adding about 10% of  HCl.
  • The one has to collect the crude product through the use of vacuum filtration.
  • Lastly one then Recrystallize from hot ethanol.
<h3>What is Electrophilic aromatic substitution?</h3>

The Electrophilic aromatic substitution is known to be a kind of an organic reaction where an atom is said to be added or attached to a kind of aromatic structure (that is made up of hydrogen) is said to be replaced by an electrophile.

Sladkaya [172]
A ground state electron configuration follows the Aufbau Principle that states that electrons should be filled up in orbitals in increasing energy. In the given sequences, the right configuration is <span>1s2 2s2 2p6 3s2 3p6 4s2 3d8. The choice that conforms to this sequence is D. In 2) the possible confirmation that follows Aufbau's principle is D. </span>
