Answer: On the basis of electrical conductivity, materials are classified as conductors, semi-conductors and non-conductors. Conductors : Substances through which electricity can easily pass through are known as conductors. ... For example, glass, wood are non-conductors. Wood is used to make tables, desks etc.
Well give me the options lol
Solution :
Molar mass of
is :
M = 6×12 + 6×1 g
M = 78 g
78 gram of
contains
molecules.
So, 89.5 gram of
contains :
![n = 6.022 \times 10^{23} \times \dfrac{89.5}{78}\\\\n = 6.91 \times 10^{23}](https://tex.z-dn.net/?f=n%20%3D%206.022%20%5Ctimes%2010%5E%7B23%7D%20%5Ctimes%20%5Cdfrac%7B89.5%7D%7B78%7D%5C%5C%5C%5Cn%20%3D%206.91%20%5Ctimes%2010%5E%7B23%7D)
Now, from the formula we can see that one molecule of
contains 2 hydrogen atom . So, number of hydrogen atom are :
![h = 2\times 6.91 \times 10^{23}\\\\h = 1.38 \times 10^{22}\ atoms](https://tex.z-dn.net/?f=h%20%3D%202%5Ctimes%206.91%20%5Ctimes%2010%5E%7B23%7D%5C%5C%5C%5Ch%20%3D%201.38%20%5Ctimes%2010%5E%7B22%7D%5C%20atoms)
Hence, this is the required solution.
Answer:
![V_{2} = 29.28\,L](https://tex.z-dn.net/?f=V_%7B2%7D%20%3D%2029.28%5C%2CL)
Explanation:
Let assume that gas behaves ideally and experiments an isobaric and isothermal processes. The following relationship is applied to determined the final volume:
![\frac{V_{1}}{n_{1}} = \frac{V_{2}}{n_{2}}](https://tex.z-dn.net/?f=%5Cfrac%7BV_%7B1%7D%7D%7Bn_%7B1%7D%7D%20%3D%20%5Cfrac%7BV_%7B2%7D%7D%7Bn_%7B2%7D%7D)
![V_{2} = V_{1} \cdot \left(\frac{n_{2}}{n_{1}} \right)](https://tex.z-dn.net/?f=V_%7B2%7D%20%3D%20V_%7B1%7D%20%5Ccdot%20%5Cleft%28%5Cfrac%7Bn_%7B2%7D%7D%7Bn_%7B1%7D%7D%20%5Cright%29)
![V_{2} = (12.2\,L)\cdot \left(\frac{16.8\,moles}{7\,moles} \right)](https://tex.z-dn.net/?f=V_%7B2%7D%20%3D%20%2812.2%5C%2CL%29%5Ccdot%20%5Cleft%28%5Cfrac%7B16.8%5C%2Cmoles%7D%7B7%5C%2Cmoles%7D%20%5Cright%29)
![V_{2} = 29.28\,L](https://tex.z-dn.net/?f=V_%7B2%7D%20%3D%2029.28%5C%2CL)
