<li>(TTCE question)
Potassium permanganate is a colored compound BECAUSE both potassium and manganese are metals. </li>
</ol>
<p>TT</p>
<ol>
<li>(another T T CE) At the same temperature and pressure, 1 liter of hydrogen gas and 1 liter of neon gas have the same mass BECAUSE equal volumes of ideal gases at the same temperature and pressure contain the same number of moles. </li>
</ol>
<p>FT</p>
<p>This is from the 1994 chem test.</p>
<ol>
<li><p>T T, because transitional metal compounds are often colored, but it has to do with their d orbitals and not the fact that the two elements are metals.</p></li>
<li><p>I’ll show the work for the first one.
1L H2 (1mol/22.4L)= .044 moles H2 (2g/1mol)= .088 grams
1L N2 (1mol/22.4L)= .044 moles N2 (28g/1mol)= 1.232 grams</p></li>
</ol>
<p>Clearly, different masses, so the first part is false.</p>
<p>This is a restatement of a scientific principle, I believe it’s called Avogadro’s Law, or something like that, which goes something like this, at the same temperature and pressure, number of moles and volume are related by this ratio: 22.4 L per mol of something.</p>
<p>Ya for 103 it has to do with the color something emits has to do with how far the electron has to jump down from energy level to a lower one. Just saying this has to do with molecular orbitals and I think it was called the ligand theory.</p>
