Answer:
Any of various particles of matter smaller than a hydrogen atom, including the elementary particles and hadrons.
Explanation:
Find the molar mass of CH3 and divide that by 45.0. That should give a whole number and then mult that whole number by CH3 to find molecular formula to get like ( incorrect ex: C2H6) which is mult by 2
<u>Answer:</u> The number of moles of nitrogen gas is 0.505 moles.
<u>Explanation:</u>
To calculate the number of moles of nitrogen gas, we use ideal gas equation, which is:
![PV=nRT](https://tex.z-dn.net/?f=PV%3DnRT)
where,
P = pressure of the gas = 4.27 atm
V = Volume of the gas = 2.96 L
T = Temperature of the gas = ![32.0^oC=[32.0+273]K=305K](https://tex.z-dn.net/?f=32.0%5EoC%3D%5B32.0%2B273%5DK%3D305K)
R = Gas constant = ![0.0821\text{ L. atm }mol^{-1}K^{-1}](https://tex.z-dn.net/?f=0.0821%5Ctext%7B%20L.%20atm%20%7Dmol%5E%7B-1%7DK%5E%7B-1%7D)
n = number of moles of gas = ?
Putting values in above equation, we get:
![4.27atm\times 2.96L=n\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times 305K\\n=0.505mol](https://tex.z-dn.net/?f=4.27atm%5Ctimes%202.96L%3Dn%5Ctimes%200.0821%5Ctext%7B%20L%20atm%20%7Dmol%5E%7B-1%7DK%5E%7B-1%7D%5Ctimes%20305K%5C%5Cn%3D0.505mol)
Hence, the number of moles of nitrogen gas is 0.505 moles.
Answer:
The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.
