a) K[Au(OH)₄], Au = +3

b) Na₄[Fe(Cl)₆], Fe = +2

<h3>What are the general rules to find oxidation number in a coordination compound?</h3>

All oxidation numbers in a neutral compound must equal zero.
All oxidation numbers in an ion must sum up to the ion's charge.
The oxidation number of a free element is zero.
Oxidation state of Hydrogen with non metals is +1.
Oxidation state of Hydrogen with metals is -1.
Oxidation state of Oxygen is -2 except Fluorine and peroxides.
Oxidation state of Fluorine is -1.

(a) K[Au(OH)₄]

Let the oxidation number of Au be X

(+1) + X + 4(-1) = 0

X + 1 - 4 = 0

X - 3 = 0

X = +3

(b) Na₄[Fe(Cl)₆]

Let the oxidation number of Fe be Y

4(+1) + Y + 6(-1) = 0

4 + Y - 6 = 0

Y - 2 = 0

Y = +2

At elevated temperature, carbon tetrachloride decomposes to its elements: CCl4(g) C(s) 2Cl2(g). At 700 K, if the initial pressur

PIT_PIT [208]

Answer:

$K=0.0131M$

Explanation:

Hello,

In this case, the undergoing chemical reaction turns out:

$CCl_4(g) \rightleftharpoons C(s)+ 2Cl_2(g)$

In such a way, by means of the mass of law action for such reaction, which is given below:

$Kp=\frac{p_{Cl_2}^2}{p_{CCl_4}}$

And in terms of the change $x$ due to reaction extent:

$p_{CCl_4}=p_{CCl_4}^0-x\\p_{Cl_2}=2x\\p_T=p_{CCl_4}+p_{Cl_2}=1.00-x+2x\\p_T=1.00+x$

$x$ results:

$x=1.35 atm -1.00atm=0.35atm$

In such a way, Kp:

$Kp=\frac{(2x)^2}{1.00-x} =\frac{(2*0.35atm)^2}{1.00atm-0.35atm}=0.754atm$

Nonetheless, K is asked instead of Kp, thus:

$K=\frac{Kp}{(RT)^{\Delta \nu _{gas}}}$

Whereas:

$\Delta \nu _{gas}=2-1=1$

Which is the change in the moles of gaseous species chlorine and carbon tetrachloride. Hence, we finally obtain:

$K=\frac{0.754atm}{(0.082\frac{atm*L}{mol*K}*700K)^{1}}\\\\K=0.0131mol/L=0.0131M$

Best regards.

Julli [10]

For [Ni(en)³]²⁺ which is purple, the crystal field splitting energy is greater than the complex ion, [Ni(H₂O)₆]²⁺ which is green in color.
When a Lewis base id attached to the metal ion by covalent bond, then the complex ion is formed and when these complex ions are present with other ions of opposite charge or neutral charge, they will make complex compounds.
