Can Anyone Help Me With This 1999 AP Chemistry Free-Response Question...Thanks

<h2>How do I approach this and what are the answers...thanks soo much</h2>

<p>Answer the following questions regarding light and its interactions with molecules, atoms, and ions.</p>

<p>1.</p>

<pre><code> The longest wavelength of light with enough energy to break the Cl-Cl bond in Cl2(g) is 495 nm.
</code></pre>

<p>1.</p>

<pre><code> Calculate the frequency, in s-1, of the light.
</code></pre>

<p>2.</p>

<pre><code> Calculate the energy, in J, of a photon of the light.
</code></pre>

<p>3.</p>

<pre><code> Calculate the minimum energy, in kJ mol-1, of the Cl-Cl bond.
</code></pre>

<p>2.</p>

<pre><code> A certain line in the spectrum of atomic hydrogen is associated with the electronic transition in the H atom from the sixth energy level (n = 6) to the second energy level (n = 2).
</code></pre>

<p>1.</p>

<pre><code> Indicate whether the H atom emits energy or whether it absorbs energy during the transition. Justify your answer.
</code></pre>

<p>2.</p>

<pre><code> Calculate the wavelength, in nm, of the radiation associated with the spectral line.
</code></pre>

<p>3.</p>

<pre><code> Account for the observation that the amount of energy associated with the same electronic transition (n = 6 to n = 2) in the He+ ion is greater than that associated with the corresponding transition in the H atom.
</code></pre>

<p>Must you post the same question in two different threads?! AP Chem is not relevant to SAT chem at all.</p>

<p>use V=(lambda)f for a, E=hf for B, and then you're off to the races.</p>

<p>i have the same problem for hw. (maybe we go to the same school) </p>

<p>for the n=2 and n=6 question, energy is emitted since n=6 has a higher energy level </p>

<p>for the second part of that question, use the Rydberg eqn. (should be in textbook) </p>

<p>i didnt get the last part of the second question</p>
