<p>ooo no! critical reading is where i suffer and that would have been AMAZING! haha, o well.</p>
<p>so what kind of raw score would be needed for a 750?</p>
<p>how does collegeboard determine the curve anyways~ do they look at the people who missed the least amount of questions or do they just pre-determine the curve....</p>
<p>the curve is based on percentiles...i think.</p>
<p>its definitly not pre-determined, they scale it so generally speaking one test being harder than the other wouldnt affect someones score, it would be compensated for by an easier curve.</p>
<p>im thinking like -14 (14 pts off, not 14 wrong)</p>
<p>at least i hope its that generous</p>
<p>omg I realized I messed up on a really easy question which said if the concentration of HCl was 0.1M what is the pH. The pH is 1, because -log(0.1)=1 and for some reason I thought it was 2. I failed to realize that -log(1M)=0 I think this is a sign that I misinterpreted several questions. boohoo</p>
<p>Even if I do manage a decent score like 750ish, it will probably be 75 percentile or less. Won't that affect college decisions more than the actual score?</p>
<p>Hyrdride vs Hydrate Whats the difference? Hydride=metal with water????</p>
<p>hydrate has water in it, it was teh first answer in that series i believe</p>
<p>hydride = metal with hydrogen
hydrate = crystalline structure with water molecules</p>
<p>hydride is metal with H ion, hydrate is compound x (H20)</p>
<p>gases deviate at low temperatures and high pressure</p>
<p>formed diatonic gas ...p5
transition metal that can have different oxidation states ....d3
lowest ionization energy ...s1</p>
<p>^^agree.....</p>
<p>Is acetic acid stronger than HCl. I thought HCl was stronger. What was that question exactly?</p>
<p>I thought water was bent/angular. NOT linear. CO2 is linear.</p>
<p>Is CH4 square planar? I thought it was tetrahedral?</p>
<p>HCl is alot stronger than acetic acid~ water IS angular (like 104 degree angle?) CH4 is tetrahedral</p>
<p>Sorry if this is repetitive. But Bohr diagram:
1. shortest one would be the least energy.
2. excited electron would be from principal energy 1 to 2 (A I believe)
3. what about the other one? and explain please. (I don't remember the question, but I didn't know this one for sure).</p>
<p>Can I omit 4 and miss 1 and still get an 800?</p>
<p>the other one was which one represents the potential ionization energy... or something and it's the line that went to infinity...i just chose it cause... it looked right</p>
<p>ionization energy is energy required to remove an electron, so it's the one where the line goes to infinity-meaning it left the atom</p>
