<p>Hey everyone, if anyone could help me with these questions, that would be phenomenal!</p>
<li><p>Anyhydrous CaCl2 removes water vapor from the atmosphere inside a container having an air-tight seal; this apparatus is a desiccator. Explain how CaCl2 removes the water vapor.</p></li>
<li><p>If anyone could help with stoichemsitry and limiting reactants, that would be great too!</p></li>
</ol>
<p>Thanks!</p>
<p>for 1, i believe that CaCl2 goes to a hydrous version, removing teh water vapor, CaCl2*XH20 (sorry, don't know what X is)</p>

<li>With stoich, you have to know your solubility rules and a solubility char helps. Limiting reagent problems aren't too bad, just a little more work. The way i do them is to do the problem using each of the information given. The limiting reagent is the one that makes less.</li>

<p>i know stuff about stoichiometry and limiting reactants, but what do you need to know? Also I think CaCl2 changes to CaCl2(dot)H20 (becomes a hydrate). I hope that helped a little.</p>
