<p>What was the decay question…?</p>
<p>Beta Particle is an electron (at least when it’s not a Positron)</p>
<p>I thought the compound with highest melting point was NaAt because most electrons ==> LD forces? And aren’t electrolytes used to measure acidity, i thought indicators were only form finding equivalence point</p>
<p>can anyone put a consolidated list?</p>
<p>it said like all of the following is true of an electron- and then it went through like its released in a nuclear decay, its a 1/3 of a mass of the atom etc</p>
<p>Oh I remember</p>
<p>Its not 1/3 of the mass</p>
<p>It is NaF because the molecule is more ionic than the others and has stronger dipole-dipole forces. Indicators show you the relative acidity by showing the endpoint which can approximate the equivalence point of an acid.</p>
<p>^ litmus and pH paper are indicators.</p>
<p>I think I got 65 for the zinc question, not 13. Wasn’t the math 1.2E24/6E23 x 1/2 x 65?</p>

I googled and found this
</p>
<p>[Does</a> NaF or NaAt have higher boiling/lower melting points? - Yahoo! Answers](<a href=“http://■■■■■■■■■■■■■■■■■/question/index?qid=20090606072833AA3Y0wb]Does”>http://■■■■■■■■■■■■■■■■■/question/index?qid=20090606072833AA3Y0wb)</p>
<p>C has the highest first ionization energy</p>
<p>Can anyone remind me of the Zinc question?</p>
<p>@apache That’s what I put. London dispersion forces increase by mass (due to increase of #e). So I put NaAt too.</p>
<p>@violinplayer
Uh…which question was that (describe it please) and what were the options?</p>
<p>@Violinplayer No it was definitely Cl</p>
<p>Also, do you guys remember how they asked the water displacement question? I can’t remeber if they ask what cant be collected or what can be. I put HCl as an answer though (thinking that it cant be collected)</p>
<p>One of the matching questions in Part A</p>
<p>didnt the question ask the lowest ionization energy</p>
<p>@apache
HCl is water soluble (polar) and so is water so HCl wouldnt be an option. I put O2 and H2</p>
<p>@Apache513 I recall that it asked which gasses could be collected. The answer was “I and II” (H2 and O2)</p>
<p>Just finished the test, I think it was okay…</p>
