Answer:

2 Cl + 2 e⁻ → 2 Cl⁻

Explanation:

<em>Which equation describes a reduction?</em>

<em>Mg(s) → Mg²⁺(aq) + 2 e⁻.</em> NO. This is an oxidation because Mg loses electrons and its oxidation number increases from 0 to 2.

<em>2 Cl + 2 e⁻ → 2 Cl⁻.</em> YES. This is a reduction because Cl gains electrons and its oxidation number decreases from 0 to 1-.

<em>Na(s) → Na⁺(aq) + e⁻.</em> NO. This is an oxidation because Na loses electrons and its oxidation number increases from 0 to 1.

<em>Al(s) → Al³⁺(aq) + 3 e⁻.</em> NO. This is an oxidation because Al loses electrons and its oxidation number increases from 0 to 3.

Ammonia will decompose into nitrogen and hydrogen at high temperature. An industrial chemist studying this reaction fills a 500.

Answer:

12. is the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture.

Explanation:

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

initially

3.0 atm 0 0

At equilibrium

(3.0-2p) p 3p

Equilibrium partial pressure of nitrogen gas = p = 0.90 atm

The expression of a pressure equilibrium constant will be given by :

$K_p=\frac{p_{N_2}\times (p_{H_2})^3}{(p_{NH_3})^2}$

$K_p=\frac{p\times (3p)^3}{(3.0-2p)^2}$

$=\frac{0.90 atm\times (3\times 0.90 atm)^3}{(3.0-2\times 0.90 atm)^2}$

$K_p=12.30\approx 12.$

12. is the pressure equilibrium constant for the decomposition of ammonia at the final temperature of the mixture.
