Answer:
Explanation:
Hello,
In this case, since the law of conservation of mass allows us to notice that the mass of carbon in the burned compound is also present in the resulting carbon dioxide, we can compute such moles as shown below:
Next, hydrogen in the sample is present at the products in the water only, and in one mole of water, two moles of hydrogen are present, thereby:
Nevertheless, the amount of oxygen in the sample must be computed by subtracting both the mass of carbon and hydrogen from the previously computed moles:
And the moles:
Next, we compute the mole ratios with respect to the element having the smallest number of moles (oxygen) to obtain the subscripts in the empirical formula:
Then, we have:
Finally, by multiplying by two, we obtain the smallest whole subscripts:
Best regards.
<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Molar mass is defined as the sum of the atoms present in a compound each multiplied with the number of atoms present in it.
For a compound 
The molar mass will be = ![[(x\times \text{Molar mass of A})+(y\times \text{Molar mass of B})]](https://tex.z-dn.net/?f=%5B%28x%5Ctimes%20%5Ctext%7BMolar%20mass%20of%20A%7D%29%2B%28y%5Ctimes%20%5Ctext%7BMolar%20mass%20of%20B%7D%29%5D)
So, for the given compound 
,
The molar mass will be = ![[(1\times \text{Molar mass of Niyrogen})+(3\times \text{Molar mass of Hydrogen})]](https://tex.z-dn.net/?f=%5B%281%5Ctimes%20%5Ctext%7BMolar%20mass%20of%20Niyrogen%7D%29%2B%283%5Ctimes%20%5Ctext%7BMolar%20mass%20of%20Hydrogen%7D%29%5D)
Hence, the correct answer is Option C.

Explanation:
Answer:
The corona shines only about half as brightly as the Moon and is normally not visible to the unaided eye, because its light is overwhelmed by the brilliance of the solar surface. During a total solar eclipse, however, the Moon blocks out the light from the photosphere, permitting eye observations of the corona.
Explanation:
Generally, mating outside of a given population can give different alleles. Mutations and the crossing over of chromatids can add difference to the genetic pool.
