Becuase they need special equipment and things like that that may not be available in the state i think
Answer:
Equilibrium constant of the given reaction is ![1.3\times 10^{-29}](https://tex.z-dn.net/?f=1.3%5Ctimes%2010%5E%7B-29%7D)
Explanation:
....![(K_{p})_{1}=5.3](https://tex.z-dn.net/?f=%28K_%7Bp%7D%29_%7B1%7D%3D5.3)
....![(K_{p})_{2}=2.1\times 10^{30}](https://tex.z-dn.net/?f=%28K_%7Bp%7D%29_%7B2%7D%3D2.1%5Ctimes%2010%5E%7B30%7D)
The given reaction can be written as summation of the following reaction-
![2NO+Br_{2}\rightleftharpoons 2NOBr](https://tex.z-dn.net/?f=2NO%2BBr_%7B2%7D%5Crightleftharpoons%202NOBr)
![N_{2}+O_{2}\rightleftharpoons 2NO](https://tex.z-dn.net/?f=N_%7B2%7D%2BO_%7B2%7D%5Crightleftharpoons%202NO)
......................................................................................
![N_{2}+O_{2}+Br_{2}\rightleftharpoons 2NOBr](https://tex.z-dn.net/?f=N_%7B2%7D%2BO_%7B2%7D%2BBr_%7B2%7D%5Crightleftharpoons%202NOBr)
Equilibrium constant of this reaction is given as-
![\frac{[NOBr]^{2}}{[N_{2}][O_{2}][Br_{2}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BNOBr%5D%5E%7B2%7D%7D%7B%5BN_%7B2%7D%5D%5BO_%7B2%7D%5D%5BBr_%7B2%7D%5D%7D)
![=(\frac{[NOBr]}{[NO][Br_{2}]^{\frac{1}{2}}})^{2}(\frac{[NO]^{2}}{[N_{2}][O_{2}]})](https://tex.z-dn.net/?f=%3D%28%5Cfrac%7B%5BNOBr%5D%7D%7B%5BNO%5D%5BBr_%7B2%7D%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%7D%29%5E%7B2%7D%28%5Cfrac%7B%5BNO%5D%5E%7B2%7D%7D%7B%5BN_%7B2%7D%5D%5BO_%7B2%7D%5D%7D%29)
![=\frac{(K_{p})_{1}^{2}}{(K_{p})_{2}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%28K_%7Bp%7D%29_%7B1%7D%5E%7B2%7D%7D%7B%28K_%7Bp%7D%29_%7B2%7D%7D)
![=\frac{(5.3)^{2}}{2.1\times 10^{30}}=1.3\times 10^{-29}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%285.3%29%5E%7B2%7D%7D%7B2.1%5Ctimes%2010%5E%7B30%7D%7D%3D1.3%5Ctimes%2010%5E%7B-29%7D)
Answer:
Element.
Explanation:
Aluminum is an element because it is not separable into simpler substances. One thing important to keep in mind is that if something is on the Periodic Table of Elements, it is 100% an element.
Answer:
A
Explanation:
Unconfined aquifers are those into which water seeps from the ground surface directly above the aquifer. Confined aquifers are those in which an impermeable dirt/rock layer exists that prevents water from seeping into the aquifer from the ground surface located directly above.
