miss Akunina [59]

Explanation:

Since, the given reaction is as follows.

$2NO(g) + Cl_{2} \rightleftharpoons 2NOCl$

Expression for $Q_{c}$ of this reaction is as follows.

$Q_{c} = \frac{[NOCl]^{2}}{[NO]^{2}[Cl_{2}]}$

Putting the given values into the above formula as follows.

$Q_{c} = \frac{[NOCl]^{2}}{[NO]^{2}[Cl_{2}]}$

= $\frac{(9.50)^{2}}{(4.40 \times 10^{-2})^{2} \times (1.80 \times 10^{-3})}$

= $\frac{90.25}{34.848 \times 10^{-7}}$

= $2.59 \times 10^{-7}$

Thus, we can conclude that $Q_{c}$ for the experiment is $2.59 \times 10^{-7}$ .

For a molecule of hydrazoic acid (HN3, also known as hydrogen azide), the atoms are arranged as HNNN. One resonance form of HN3

disa [49]

Answer:

0; +1; -1

Explanation:

The resonance structure of HN₃ is shown below (you can also use horizontal dashes to represent the bonding pairs).

The molecule has 16 valence electrons, and each N atom has an octet.

To get the formal charges, cut the covalent bonds in half.

Each atom gets the electrons on its side of the cut.

Formal charge = valence electrons in isolated atom - electrons on bonded atom

FC = VE - BE

(a) On Nₐ

VE = 5

BE = 1 lone pair (2)+ 3 bonding electrons = 2 + 3 = 5

FC = 5 - 5 = 0.

(b) On Nb:

VE = 5

BE = 4 bonding electrons = 4

FC = 5 - 4 = +1

(c) On Nc:

VE = 6

BE = 2 lone pairs(4) + 2 bonding electrons = 4 + 2 = 6

FC = 5 - 6 = -1
