Answer:
The incorrect statement is option B and D.
Explanation:
Carbohydrates are more generally is known as the sugars that are composed of the carbon, hydrogen and oxygen atoms. Monosaccharides are the single unit of carbohydrates while disaccharides are the sugars that contain two molecules of the sugar and similarly saccharides with multiple sugars are called polysaccharides. The general chemical formula of the carbohydrates Cn(H2O)n, however the complex sugars does not follow this formula. Amino sugars are contains NH2 in their formula so carbohydrates not necessarily contains only H, O, AND C always.
Thus, the incorrect answer is - option B and D.
<u>Answer:</u> The wavelength of spectral line is 656 nm
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:
![\frac{1}{\lambda}=R_H\left(\frac{1}{n_f^2}-\frac{1}{n_i^2} \right )](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Clambda%7D%3DR_H%5Cleft%28%5Cfrac%7B1%7D%7Bn_f%5E2%7D-%5Cfrac%7B1%7D%7Bn_i%5E2%7D%20%5Cright%20%29)
Where,
= Wavelength of radiation
= Rydberg's Constant = ![1.097\times 10^7m^{-1}](https://tex.z-dn.net/?f=1.097%5Ctimes%2010%5E7m%5E%7B-1%7D)
= Final energy level = 2
= Initial energy level = 3
Putting the values in above equation, we get:
![\frac{1}{\lambda }=1.097\times 10^7m^{-1}\left(\frac{1}{2^2}-\frac{1}{3^2} \right )\\\\\lambda =\frac{1}{1.524\times 10^6m^{-1}}=6.56\times 10^{-7}m](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Clambda%20%7D%3D1.097%5Ctimes%2010%5E7m%5E%7B-1%7D%5Cleft%28%5Cfrac%7B1%7D%7B2%5E2%7D-%5Cfrac%7B1%7D%7B3%5E2%7D%20%5Cright%20%29%5C%5C%5C%5C%5Clambda%20%3D%5Cfrac%7B1%7D%7B1.524%5Ctimes%2010%5E6m%5E%7B-1%7D%7D%3D6.56%5Ctimes%2010%5E%7B-7%7Dm)
Converting this into nanometers, we use the conversion factor:
![1m=10^9nm](https://tex.z-dn.net/?f=1m%3D10%5E9nm)
So, ![6.56\times 10^{-7}m\times (\frac{10^9nm}{1m})=656nm](https://tex.z-dn.net/?f=6.56%5Ctimes%2010%5E%7B-7%7Dm%5Ctimes%20%28%5Cfrac%7B10%5E9nm%7D%7B1m%7D%29%3D656nm)
Hence, the wavelength of spectral line is 656 nm
The answer to your question is D.
Given the criteria, there are six because there are three Carbon dioxide molecules and di means two; so two times three us six. But if u look at the whole reaction *pictured below* u will see that in the entire reaction there are 10 Oxygen reacting through the whole thing.
*the triangle is the Greek letter delta and it symbolizes heat in a reaction.
Answer:
it should be the second one since London dispersion causes interaction between molecules.
hope I helped.
