Answer:
20.5 torr
Explanation:
Given parameters:
Volume of tank = 15L
Pressure of tank = 8.2 x 10⁴torr
Volume of empty chamber = 6.0 x 10⁴L
Unknown:
New pressure of the gas in this chamber = ?
Solution:
To solve this problem, a good knowledge of the gas law will suffice here. Since pressure and volume relationships are under consideration, the Boyle's law is the proper gas law to apply.
Boyle's law states that "at constant temperature, the volume of fixed mass of gas is inversely proportional to the pressure of the gas".
Mathematically;
(Pressure x volume) of tank = (Pressure x volume ) of empty chamber
15 x 8.2 x 10⁴ = Pressure of empty chamber x 6 x 10⁴
Pressure of empty chamber = 20.5 torr
Answer:
The rate of disappearance of 
for this period is
Explanation:
Initial concentration of = x = 0.0138 M
Final concentration of = y = 0.00886 M
Time elapsed during change in concentration = Δt = 374 s
Change in concentration ,![\Delta [NO_2]](https://tex.z-dn.net/?f=%5CDelta%20%5BNO_2%5D)
= y - x = 0.00886 - 0.0138 M = -0.00494 M
The rate of disappearance of for this period is:
![\frac{\Delta [NO_2]}{\Delta t}=\frac{-0.00494 M}{374 s}=-1.32\times 10^{-5} M/s](https://tex.z-dn.net/?f=%5Cfrac%7B%5CDelta%20%5BNO_2%5D%7D%7B%5CDelta%20t%7D%3D%5Cfrac%7B-0.00494%20M%7D%7B374%20s%7D%3D-1.32%5Ctimes%2010%5E%7B-5%7D%20M%2Fs)
Seeds come from adult plants. They're made from plants to make more plants.
The term referring to that region would be "orbital".
