3241004551 [841]

Answer:

The correct answer is: <em>They each partially describe the bonding in a molecule.</em>

Explanation:

Some chemical molecules cannot be described completely by using only one Lewis structure. In these cases, we can describe the molecule by drawing 2 or more Lewis structures, and the structures are called <u>resonance structures</u>. The overall molecular structure is explained by all the resonance structures together. So, they each describe the bonding in the molecule only partially.

Dinitrogentetraoxide partially decomposes into nitrogen dioxide. A 1.00-L flask is charged with 0.0400 mol of N2O4. At equilibri

artcher [175]

Answer:

Keq=0.866

Explanation:

Hello,

In this case, the undergone chemical reaction is:

$N_2O_42NO_2$

In such a way, since 0.0055 mol of N₂O₄ remains in the flask, one infers that the reacted amount ( $x$ ) was:

$x=0.04mol-0.0055mol=0.0345mol$

In addition, the produced amount of NO₂ is:

$2*0.0345mol=0.069mol$

Finally, considering the flask's volume, the equilibrium constant is then computed as follows:

$Keq=\frac{(2*0.0345M)^2}{0.0055M}=0.866$

Best regards.

7. A gas has a volume of 300 mL at 300 mm Hg. What will its volume be if the pressure is changed to 500 mm Hg?

USPshnik [31]

Answer:

The volume is

<h2>180 mL</h2>

Explanation:

In order to solve for the volume we use the formula for Boyle's law which is

<h3> $P _{1} V _{1} = P _{2}V _{2}$ </h3>

where

P1 is the initial pressure

V1 is the initial volume

P2 is the final pressure

V2 is the final volume

Since we are finding the final volume we are finding V2

Making V2 the subject we have

<h3> $V _{2} = \frac{P _{1} V _{1}}{P _{2} }$ </h3>

From the question

P1 = 300 mmHg

V1 = 300 mL

P2 = 500 mmHg

Substitute the values into the above formula and solve for the final volume obtained

That's

<h3> $V _{2} = \frac{300 \times 300}{500} \\ = \frac{90000}{500} \\ = \frac{900}{5}$ </h3>

We have the final answer as

<h3>180 mL</h3>

Hope this helps you
