The chemical reaction is as follows:

<span>2NH3(g) = N2(g) + 3H2(g)

We do the ice method to answer this. 
                
            NH3            N2             H2
I          1.22              0                0
C          -2x              x                3x 
E        1.22 - 2x       x                3x

Kc = [h2]^3 [n2] / [nh3]^2
</span>4.0 × 10^–2 = 27x^3(x) /  (1.22 - 2x )^2
x = 0.259 mol

H2 = 0.259/1 = 0.259 mol/L

What neutral element has the electron configuration described by the Aufbau diagram above.​
devlian [24]

Answer:

Aluminium.

Explanation:

The above electronic configuration can be written in a simplified form as shown below:

1s² 2s²2p⁶ 3s²3p¹

Next, we shall determine the number of electrons in the atom of the element as follow:

Number electron = 2 + 2 + 6 + 2 + 1

Number of electron = 13

Next, we shall determine the number of protons.

Since the element is in its neutral state,

The number of electrons and protons are equal i.e

Proton = Electron

Number of electron = 13

Proton = Electron = 13

Proton = 13

Next, we shall determine the atomic number of the element.

The atomic number of an element is simply the number of protons in the atom of the element i.e

Atomic number = proton number

Proton = 13

Atomic number = 13

Comparing the atomic number of the element with those in the periodic table, the element with the above electronic configuration is aluminium since no two elements have the same atomic number.

A variation of the acetamidomalonate synthesis can be used to synthesize serine. The process involves the following steps: Ethox
Alex73 [517]

Answer:

See detailed mechanism in the image attached

Explanation:

The mechanism shown in detail below is the synthesis of serine in steps.

The first step is the attack of the ethoxide ion base on the diethyl acetamidomalonate substrate giving the enolate and formaldehyde.

The second step is the protonation of the oxyanion from (1) above to form an alcohol as shown.

Acid hydrolysis of the alcohol formed in (3) above yields a tetrahedral intermediate, a dicarboxyamino alcohol.

Decarboxylation of this dicarboxyamino alcohol yields serine, the final product as shown in the image attached.

Answer:

Observe: To model how hydrogen and oxygen react to make water, type “H2+O2” into the Reactants box and “H2O” into the Products box.

As the equation is written, which element is not in balanced?

oxygen isn't balanced...

Explanation:

in reactants there is 2hydrogens and 2 oxygen

but in product there is balanced no if hydrogen bt there is only one no of oxygen
