<p>Pretty sure you’re wrong again. I remember it as adding acid to water, which is correct. I don’t believe heating up a GRADUATED CYLINDER is proper, however.</p>
<p>Sheheiruddin,</p>
<p>Or you could go on [Unpaired</a> electron - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Unpaired_electron]Unpaired”>Unpaired electron - Wikipedia). :[</p>
<p>Archon, you ALWAYS add water to acid. It was a huge sign in a lab at Columbia.</p>
<p>wat about he covaent bond question? I put 3 i dunno lol it was confusing</p>
<p>no im right it was the same EXACT question from the may exam which i took…lol sigh</p>
<p>im referring to the lab question btw</p>
<p>No…the p orbital can hold a total of 6 electrons. After 3 e- are “added” the next ones must pair up. Thus, moving left to right you’ll have 1 2 3 2 1 0 unpaired electrons , with the first 1 being of the Boron group and 0 being a Noble gas.</p>
<p>So, the answer was 3.</p>
<p>you can NEVER add acid to water unless the water is COMPLETELY dilute</p>
<p>dude its 6 just live with it besides</p>
<p>79-80/85 is almost always 800.</p>
<p>You are always supposed to add acid to water, never the other way. And you would never heat a graduated cylinder.</p>
<p>

<p>
</p>
<p>/facepalm</p>
<p>Christ, now I remember why I rarely frequent these forums.</p>
<p>you add acid to water. That’s just it. The wrong answer was the one about heating and graduated cylinder?</p>
<p>
</p>
<p>You are correct. I wouldn’t base an estimate of my score off this thread…</p>
<p>Ok… the answer is 6, let’s all pretend it was 6 so he just shuts the ■■■ up. because we all know it’s 3… even wikipedia effing says it’s 3.</p>
<p>So in an effort to make this kid shut up. ok it’s 6, you’re right </p>
<p>btw what was the answer for adding 30 ml of .1 M KOH to a 60 ml unknown monoprotic acid?</p>
<p>Oops I’m wrong. :]</p>
<p>so which one was the incorrect lab procedure?
also, what was the only one found in nature as a free element?</p>
<p>It said which one was NOT found as a free element, which is Na because it is highly reactive.</p>
<p>look in to the may 2009 exam thread and you’ll see what I’m talking about.</p>
<p>Water Displacement question?</p>
<p>so far i have all the matching and T/F correct couple of multiple questions wrong though sigh…</p>
<p>aiming for 770+</p>
<p>
I don’t even know what question you’re talking about, but I’m sure you’re right, especially after seeing your fantastic track record with other problems /sarcasm</p>
<p>please pick up a chem book and learn the concept of electrons as opposed to electron domains/pairs/orbitals. Each electron domain holds two electrons, each with opposite spins.</p>
<p>Incorrect lab procedure: wouldn’t it be pouring an acid into water? It should be the other way around, pouring water into the acid.</p>
