As an EPA scientist studying catalytic converters and urban smog, you want to find Kc for the following reaction: 2NO2(g) ⇋ N2(g
Bas_tet [7]

Answer:

Kc = 4.774 * 10¹³

Explanation:

the desired reaction is

2 NO₂(g) ⇋ N₂(g) + 2 O₂(g)

Kc =[N₂]*[O₂]² /[NO₂]²

Since

1/2 N₂(g) + 1/2 O₂(g) ⇋ NO(g)

Kc₁= [NO]/(√[N₂]√[O₂]) →  Kc₁²= [NO]²/([N₂][O₂])

and

2 NO₂(g) ⇋ 2 NO(g) + O₂(g)

Kc₂= [NO]²*[O₂]/[NO₂]² →  1/Kc₂= [NO₂]²/([NO]²[O₂])

then

Kc₁²* (1/Kc₂) = [NO]²/([N₂]*[O₂]) *[NO₂]²/([NO]²[O₂])  = [NO₂]²/([N₂]*[O₂]²) = 1/Kc

Kc₁² /Kc₂ = 1/Kc

Kc= Kc₂/Kc₁² =1.1*10⁻⁵/(4.8*10⁻¹⁰)² = 4.774 * 10¹³

What is the relationship between mass and the end stages of stars
aleksandr82 [10.1K]
The mass of stars affect how they end. 

Stars with greater mass sometimes end with supernovas, a giant explosion, which can result in black holes or neutron stars, or sometimes nothing.

A medium sized star can result in a planetary nebula, which then results in a white dwarf.

Haha hope this sorta helped :)

A scientist develops a new experiment to test atomic theory. His results do not agree with the theory.
slamgirl [31]

Answer:

When the results of a new experiment to test atomic theory do not agree with the theory, scientist will repeat the experiment to make sure that his results are reliable.

Explanation:

In the scientific context, each new experiment must be performed with precision and following the steps of the scientific method.

An experiment that does not provide reliable data to demonstrate a theory must be reviewed in detail and performed again to confirm the data obtained in the first attempt.

A theory is a postulate that tries to explain a natural phenomenon, but whose argument can be discussed or does not have the acceptance of a law. When the theory is proven and there are no arguments against it, it can be universally accepted and becomes a law.

The other options are not valid due to:

  • <u><em>Scientists worldwide will reject atomic theory because of the new results</em></u><em>.  A theory cannot be discarded without solid arguments or evidence in order to dismiss it and establish a new one.</em>
  • <u><em>The scientist will change his results to agree with the accepted theory</em></u><em>.  This would be an unethical procedure and unacceptable to the scientific community.</em>
  • <em><u>Other scientists will reject the results because they do not agree with the theory</u></em><em>. The opinion of other scientists is not enough to dismiss a theory, if it has a valid scientific basis.</em>
