The skeletal structure of an organic compound is an abbreviated representation of its molecular structure, they are quick and easy to draw.
For example, the following image shows the skeletal structure of a compound:
The peaks represent the carbons. We must remember that carbon can have a maximum of 4 bonds.
Now, I will show you how is the structure of this specific compound:
This is ternary alcohol, called 2-methyl-2-butanol. If you see carefully, you will notice that each carbon has 4 bonds. The functional groups present will be OH. The skeletal structure will be:
There are 0.454 kg in 1 lb
Cross multiply
0.454 kg = 1 lb
X kg. = 50 lb
50* 0.454 = 22.7 kg
Answer : 22.7 kg in 50 lbs
Answer:
1 tablet
Explanation:
Assuming that gm stands for gram:
Put everything in one unit, 0.3 g = 300 mg.
And given that each tablet is 300 mg:
mass/amount = 300mg / 1 tablet
300mg / X amount = 300mg / 1 tablet
(300mg/300mg) tablet = X = 1 tablet
So it is 1 tablet you need.
Answer: The wavelength of the x-ray wave is ![10^{-10}m](https://tex.z-dn.net/?f=10%5E%7B-10%7Dm)
Explanation:
To calculate the wavelength of light, we use the equation:
![\lambda=\frac{c}{\nu}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7Bc%7D%7B%5Cnu%7D)
where,
= wavelength of the light = ?
c = speed of x-ray= ![3.0\times 10^8m/s](https://tex.z-dn.net/?f=3.0%5Ctimes%2010%5E8m%2Fs)
= frequency of x-ray =
![(1Hz=1s^{-1})](https://tex.z-dn.net/?f=%281Hz%3D1s%5E%7B-1%7D%29)
Putting in the values:
![\lambda=\frac{3.0\times 10^8m/s}{3.0\times 10^{18}s^{-1}}=10^{-10}m](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7B3.0%5Ctimes%2010%5E8m%2Fs%7D%7B3.0%5Ctimes%2010%5E%7B18%7Ds%5E%7B-1%7D%7D%3D10%5E%7B-10%7Dm)
Thus the wavelength of the x-ray wave is ![10^{-10}m](https://tex.z-dn.net/?f=10%5E%7B-10%7Dm)
