How does a physical change differ from a chemical change
inysia [295]

With a physical change you can actually see it change like ice turning into water, then with a chemical change you can't see it change, although within the molecules themselves they change which makes that possible.


Hope this helps!

Fluorine is a toxic, reactive gas. which representation (structural formula, electron dot structure, or three-dimensional model)
Hoochie [10]
The representation that would best explain the properties of the gas fluorine would be a <span>electron dot structure. From this structure, you can see how many electrons are available for bonding since the electrons are the ones responsible for interacting with other atoms. </span>

If a reaction vessel at that temperature initially contains 0.0400 M NO2 and 0.0400 M N2O4, what is the concentration of NO2 at
LenaWriter [7]

Answer:

0.088 M.

Explanation:

Assuming that the temperature is 429 K, we can calculate the concentration of NO₂. Kc(429K) = 0.490.

The reaction is:

N₂O₄(g)  ⇄  2NO₂(g)

0.04             0.04

0.04 - x          0.04 + 2x

The constant of the reaction is:

Kc = \frac{[NO_{2}]^{2}}{[N_{2}O_{4}]]}

0.490 = \frac{(0.04 + 2x)^{2}}{0.04 - x}

0.490*(0.04 - x) - (0.04 + 2x)^{2} = 0

By solving the above equation for x we have:

x = 0.024 = [NO₂]      

Hence the concentration of NO₂ is:

[NO_{2}] = 0.04 + 2*0.024 = 0.088 M

I hope it helps you!
