<p>So I skipped 12
I doubt I got the rest of the 73 right
Shall we discuss?</p>
<p>I’m game. What did you get for the balancing question that had like Ca+2 in it and CO3 and H2O and a bunch of other stuff? I can’t remember the full reaction as it had a lot of reactants and products, but I think my answer was D/coefficient of 4. What did you get?</p>
<p>Ummm
there were soo many I dont remember
Ugh
Ionic compounds arent brittle are they?
But they do conduct electricity right?
DO u remember that question?
And last question was it heat of sublimation?</p>
<p>I think it was heat of sublimation, that’s what I put because it went from a solid to a gas which is sublimation. The one about conducting electricity when a liquid or aqueous solution I put down either an ionic bond or ionic compound, can’t remember the actual choices.</p>
<p>i think i put london dispersion forces for one of them
…
i bombed
wanted at least 750+
Oh well
Was the answer sublimation for the purple vapor above the iodin crystals?</p>
<p>I thought it was an ionic compound.</p>
<p>but theyre not brittle
idr
how many grams did u get for the one with how many grams of Zn from 1.2x10^24 atoms
something like that</p>
<p>NaCl, table salt, is an ionic compound that is brittle.
When it’s melted, it makes a good electrolyte.</p>
<p>wait what did u get for question…16 was it?
oh i remember
it was an ionic compound
i thought u were talking about another question
were london forces the cause for the liquefication of n2 at low temperatures?</p>
<p>[YouTube</a> - Sublimation of Iodine](<a href=“Sublimation of Iodine - YouTube”>Sublimation of Iodine - YouTube)</p>
<p>Iodine, solid, sublimating into purple gas.</p>
<p>:O
thank you
aight so i got that right
am i right about the london disperesion forces and N2???</p>
<p>N2 is a nonpolar covalent, which means it has the weakest intermolecular force which is LDF. So yes, LDF is the cause for the liquefaction of N2 at low temperature.</p>
<ol>
<li>Nonpolar molecules do not have permanent dipoles.
However, the instantaneous electron distribution in a molecule can be asymmetric.
The resultant transient dipole moment can induce a dipole in an adjacent molecule. This induced dipole- induced dipole interaction (London dispersion force), with a force of 0.5-1 kcal /mol, is sufficient to facilitate
order in a molecular array. These relatively weak electrostatic forces are responsible for the liquefaction of nonpolar gases.</li>

<p>yesssssssss
confidence: +100
did u get 6.5 grams for a question about zinc and silver and like 1.2x10^24 atoms
does that ring bell</p>
<p>I don’t remember that question that well… I know it was simple stoichiometry question though</p>
<p>there was more converting
did u put magnet and cardboard for sulfur and iron fillings??</p>
<p>Oh 1.2 X 10^24 meant two moles of whatever which was one mole zinc solid which was 53 ish grams.</p>
<p>And ya magnet. Was the one not found naturally sulfur?</p>
<p>i put magnet and cardboard for sulfur and iron fillings… what did u put for the unsafe laboratory procedure?? i never studied that stuff</p>
<p>@ hardworking: I was stuck between two… i ended up putting Na because i thought, it is way too reactive, while sulfur is less reactive. According to wiki, Na is the answer –> " Elemental sodium does not occur naturally on Earth, because it quickly oxidizes in air[2] and is violently reactive with water, so it must be stored in a non-oxidizing medium, such as a liquid hydrocarbon."</p>
<p>there were 4 ces</p>
<p>the last one about co2 polar and linear
the one about NaOH dissociated into OH-
and two others</p>
