How natural plants and wetlands purify water

1 answer:

7 0

Plants and wetlands purify water by acting as filter media. The roots of the plants and the wetlands would trap pollutants like sediments and hold onto the. In wetlands, the flow of water is slow allowing for the sediments to settle due to gravity onto the bottom where the plants would accumulate them into place. With this, excess nutrients would be remove and will prevent polluting bodies of water. Also, bacteria like E. coli and Salmonella can be filtered out from the water. There are plants that works excellent for filtering out pollutants like the lilies, hornwort, bulrushes and rushes.

At 2000 ∘C the equilibrium constant for the reaction 2NO(g)⇌N2(g)+O2(g) is Kc=2.4×103. If the initial concentration of NO is 0.1

Rasek [7]

Answer:

$[N_2]=0.0866M$

Explanation:

Hello there!

In this case, in agreement to the chemical reaction, it is possible for us to figure out the equilibrium concentration of the N2 product, via an ICE table plugged in the equilibrium expression:

$Kc=\frac{[N_2][O_2]}{[NO]^2}\\\\2.4x10^3=\frac{x*x}{(0.175-2x)^2}$

In such a way, when solving for x via quadratic equation or just a solver, it is possible to obtain:

$x_1=0.0866M\\\\x_2=0.0884M$

In such a way, since the root 0.0884 M produce a negative concentration of NO (0.175-2*0.0884=-0.0018M), we infer that the correct root is 0.0866 M; therefore, the concentration of N2 at equilibrium is equal to x:

$[N_2]=x=0.0866M$

Best regards!

Answer:

Following are the solution to these question:

Explanation:

Simple diffusion implies which molecules can move across a cell membrane instead of using the incorporated protein structure channels. Its flow of molecules across these canals is enabled by diffusion. It has steroid hormones and N2.

Facilitated diffusion of molecules via cell membranes, or active transportation, which would be the random mass transit process of molecules or ions via unique cellular membranes from the transmembrane. It has K+ and Glucose.
