Answer:
8 grams
Explanation:
The molar mass of CH4 is about 16 grams per mol. So you get the answer by mutlitplying 0.5 by 16, (cancel out moles by placing 1 on the bottom of the fraction).
Answer:
Explanation:
From the information given:
oxidation of oxidized solution takes place at 950° C
For wet oxidation:
The linear and parabolic coefficient can be computed as:
![\dfrac{B}{B/A} = D_o \ exp \Big [\dfrac{-\varepsilon a}{k_BT} \Big]](https://tex.z-dn.net/?f=%5Cdfrac%7BB%7D%7BB%2FA%7D%20%3D%20D_o%20%5C%20exp%20%5CBig%20%5B%5Cdfrac%7B-%5Cvarepsilon%20a%7D%7Bk_BT%7D%20%5CBig%5D)
Using
and
values obtained from the graph:
Thus;
![\dfrac{B}{A} = 1.63 \times 10^8 exp \Big [ \dfrac{-2.05}{8.617 \times 10^{_-5}\times 1173}\Big] \\ \\ = 0.2535 \ \ \mu m/hr](https://tex.z-dn.net/?f=%5Cdfrac%7BB%7D%7BA%7D%20%3D%201.63%20%5Ctimes%2010%5E8%20exp%20%5CBig%20%5B%20%5Cdfrac%7B-2.05%7D%7B8.617%20%5Ctimes%2010%5E%7B_-5%7D%5Ctimes%201173%7D%5CBig%5D%20%5C%5C%20%5C%5C%20%3D%200.2535%20%5C%20%5C%20%5Cmu%20m%2Fhr)
![B= 386 \ exp \Big [-\dfrac{0.78}{8.617 \times 10^{-3} \times 1173} \Big] \\ \\ = 0.1719 \ \mu m^2/hr](https://tex.z-dn.net/?f=B%3D%20386%20%5C%20%20exp%20%5CBig%20%5B-%5Cdfrac%7B0.78%7D%7B8.617%20%5Ctimes%2010%5E%7B-3%7D%20%5Ctimes%201173%7D%20%5CBig%5D%20%5C%5C%20%5C%5C%20%20%3D%200.1719%20%5C%20%5Cmu%20m%5E2%2Fhr)
So, the initial time required to grow oxidation is expressed as:


∴


NOW;







Thus; since we will consider the positive sign, the initial thickness
is ;
≅ 0.261 μm
Temperature can be calculated using the average kinetic energy. The ideal gas equation is being related to the average molecular kinetic energy.

Answer:
0.03atm
Explanation:
Given parameters:
Total pressure = 780torr
Partial pressure of water vapor = 1.0atm
Unknown:
Partial pressure of radon = ?
Solution:
A sound knowledge of Dalton's law of partial pressure will help solve this problem.
The law states that "the total pressure of a mixture of gases is equal to the sum of the partial pressures of the constituent gases".
Mathematically;
P
= P
+ P
+ P
Since the total pressure is 780torr, convert this to atm;
760torr = 1 atm
780torr =
atm = 1.03atm
For this problem;
Total pressure = Partial pressure of radon + Partial pressure of water vapor
1.03 = Partial pressure of radon + 1.0
Partial pressure of radon = 1.03 - 1.00 = 0.03atm
Yes because it’s growing to become a flower
