Answer:
B. 091
Explanation:
When we add these two equilbria, the equilibrium constant for the resultant equilibrium is the product of the first two.
Notice that when we add the first two reactions in this question, we obtain the equilibrium for which we are seeking its equilibrium constant. Therefore,
A(g) + B(g) ? AB(g) Kc₁ = [AB] / [A][B]
+
AB(g) + A(g) ? A2B(g) Kc₂ = [A₂B] /[ AB][A]
_________________________________
2 A(g) + B(g) ⇄ A₂B(g) Kc₃ = [A₂B] / [A]²[B]
Kc₁Kc₂ = [AB] / [A][B] x [A₂B] / [AB][A] = [A₂B] / [A]²[B]
Thus,
Kc₃ = 0.24 x 3.8 = 0.91
This procedure is not limited to two reaction, it could done for more than two, as long as the desired equilibrium is the desired one.
Answer:
A photon.
Explanation:
An electron movies from a ground state to an exited state when it absorbs a photon.
Carbon fixation<span> refers to the conversion process of inorganic </span>carbon<span> (</span>carbon <span>dioxide) to organic compounds by living organisms. The most prominent example is photosynthesis, although chemo synthesis is another form of </span>carbon fixation<span> that can take place in the absence of sunlight.</span><span />
During this reaction, carbon dioxide<span> and water are converted into </span>glucose<span> and</span>oxygen<span>. The reaction requires light energy, which is absorbed by a green substance called </span>chlorophyll. Photosynthesis takes place in leaf cells. These containchloroplasts<span>, which are tiny objects containing </span>chlorophyll<span>.
Hope this helps~!

I believe it’s 3 hours since every hour it’s 80km so 3x80 is 240 so it would be 3 hours.
