Answer:
The given hydrocarbon is Ethylene Glycol
Answer:
People show more interest in personal broadcasting.
Explanation:
The art of oration (speaking) is being replaced by personal broadcasting mean now people used webcam or camcorder for creating its own content and transmit it to other people through internet. Personal broadcasting provides audio and video to the individual that make it more interesting as compared to oration. People show more interest in personal broadcasting as compared to oration so that's why oration is replaced by personal broadcasting.
Um... following where is the following plz add a pic sorry :(
Answer:
The molar mass of the gas
Explanation:
The ideal gas equation of state is:
PV = nRT
If we measure the volume (V), the pressure (P), and the temperature (T), we use the gas constant R (0.082 L.atm/K.mol) to calculate n (moles of gas):
n = PV/RT
Then, we can divide the mass into the number of moles to calculate the molar mass of the gas:
molar mass = mass/n
Answer:
![CH_5N](https://tex.z-dn.net/?f=CH_5N)
Explanation:
Hello,
Percent composition is defined as:
%
Whereas
is the subscript in the formula,
the atomic mass of the ith element and
the compound's molecular mass, thus, solving for
:
![n_i=\frac{percent*M}{100*m_i} \\n_C=\frac{38.8*M}{100*12} =0.0323M\\n_H=\frac{16.2*M}{100*1} =0.162M\\n_N=\frac{45.1*M}{100*14} =0.0322M\\](https://tex.z-dn.net/?f=n_i%3D%5Cfrac%7Bpercent%2AM%7D%7B100%2Am_i%7D%20%5C%5Cn_C%3D%5Cfrac%7B38.8%2AM%7D%7B100%2A12%7D%20%3D0.0323M%5C%5Cn_H%3D%5Cfrac%7B16.2%2AM%7D%7B100%2A1%7D%20%3D0.162M%5C%5Cn_N%3D%5Cfrac%7B45.1%2AM%7D%7B100%2A14%7D%20%3D0.0322M%5C%5C)
Now, divining each
over the least one (
) we get:
![n_C=\frac{0.0323}{0.0322}=1\\\\n_H=\frac{0.162}{0.0322}=5\\\\n_N=\frac{0.0322}{0.0322}=1](https://tex.z-dn.net/?f=n_C%3D%5Cfrac%7B0.0323%7D%7B0.0322%7D%3D1%5C%5C%5C%5Cn_H%3D%5Cfrac%7B0.162%7D%7B0.0322%7D%3D5%5C%5C%5C%5Cn_N%3D%5Cfrac%7B0.0322%7D%7B0.0322%7D%3D1)
Finally the empirical formula turns out into:
![CH_5N](https://tex.z-dn.net/?f=CH_5N)
Best regards.
