<p>1) How do you separate sand and salt? I chose the first one picture.
2) What kind of radiation does the sun give off? Ultraviolet?</p>
<p>i put the funnel for sand and salt because salt dissolves in water… sand doesn’t so that stays in the funnel while the salt and water go through the paper</p>
<p>you separate sand and salt with the filter/funnel right??</p>
<p>and then the iron and copper with the magnet</p>
<p>and what about the h2 from hcl?</p>
<p>oh my god I skipped like 13 too!!! I thought it was only me, but I see that a lot of people omitted many questions… I hope the curve is lenient… OH GOD, PLEASE.</p>
<p>for the instrument that separates the 2 gases i chose the first picture (thistle tube i think)</p>
<p>for the 2 gases I chose the last picture. Zinc dissolves in hcl to give off H2 which is insoluble in water.</p>
<p>What about the separating zinc and copper. I put the magnet.</p>
<p>Yep, iron is magnetic while copper isn’t.</p>
<p>how many did u guys omitted? i did 16 :T will i still be able to get in the 700s?</p>
<p>It will probably be a regular curve -1 or -2. My guess. 80-81 RAW = 800.</p>
<p>I omitted one…it was one of the relationship analysis questions. Based on everyone’s reactions I think the curve may be slightly more lenient…maybe -3 or 4 = 800</p>
<p>what does a -3 or -4 curve mean? :o</p>
<p>what other questions were there?
were there supposed to be THAT many math problems???</p>
<p>it just means that you can get 3 or 4 points off of your raw score and it’d still be an 800</p>
<p>ohh i see</p>
<p>how many did you guys omitted?
how a scale of 1-10 (10 being the hardest) what would u rate the test?</p>
<p>i omitted one but i know i got some wrong alraedy.
i thought it was a 9
it was so much harder that any of the practice tests i had taken.</p>
<p>@tneduts I got all the same answers as you, I hope we are right! Did you guys get one or two TTCE? I had one…</p>
<p>i had two TTCE i think</p>
<p>and that’s a good news if we all think it’s hard… it means that the curve would be “nice” to us</p>
<p>on a scale of 1-10 (10 being the hardest) what would u guys rate the test?</p>
<p>Feel free to add to this consolidated list:</p>
<p>Ionization energy, Isoelectronic, kinetic energy
The sun emits ultraviolet radiation
The earth emits infrared radiation
Salt and sand are separated with a funnel
Copper and iron are separated with a magnet
HCL and H2 gas are separated with that last picture of bubbling water
9 L of water to dilute HCL
SiCl4 is tetrahedral
Highest kinetic energy was CH4
Partial pressure of N2 is 100
Copper solution was blue
Silver and something else formed a precipitate
Phenalthapin turns BASES pink</p>
<p>I had 2 TTCEs and I’d rate it about a 7 or 8 compared to the practice tests I took</p>
