Answer:

D. Sr < Ca < Be  

Step-by-step explanation:

<em>Ionization energ</em>y decreases from top to bottom within a Group, because the valence electrons are further from the nucleus and therefore easier to remove.

Thus, <em>Sr has the lowest</em> ionization energy and <em>Be the highes</em>t.

The correct order is Sr < Ca < Be.

How does natural selection produce adaptations in a species?
pashok25 [27]

Answer: Concentration of NH_3 in the equilibrium mixture is 0.31 M

Explanation:

Equilibrium concentration of H_2 = 0.729 M

The given balanced equilibrium reaction is,

                 2NH_3(g)\rightleftharpoons N_2(g)+3H_2(g)

Initial conc.            x                0           0

At eqm. conc.     (x-2y) M     (y) M   (3y) M

The expression for equilibrium constant for this reaction will be:

3y = 0.729 M

y = 0.243 M

K_c=\frac{[y]\times [3y]^3}{[x-2y]^2}

Now put all the given values in this expression, we get :

K_c=\frac{0.243\times (0.729)^3}{(x-2\times 0.243)^2}

0.967=\frac{0.243\times (0.729)^3}{(x-2\times 0.243)^2}

x=0.80

concentration of NH_3 in the equilibrium mixture = 0.80-2\times 0.243=0.31

Thus concentration of NH_3 in the equilibrium mixture is 0.31 M
