<p>I guess that if you assume that only CaCO3 reacts, that does kind of include that you are assuming those substances all had CaCO3, right?</p>
<p>
</p>
<p>I think so. Better yet, I hope so…</p>
<p>
</p>
<p>Right, which is why you had to assume that ONLY the calcium carbonate reacted and nothing else. Which is definitely not the case in real life, which is why you were assuming it.</p>
<p>
</p>
<p>eh…thats sorta pushing it. not the best answer</p>
<p>Okay, let’s move onto another question then.</p>
<p>What was the answer to the one with the rate of something for CaCO3? I didn’t have time to come back to it, but I put B (whatever it was).</p>
<p>Also there was this graph question for the capacitor question. It was like why is the value 0 at x = 0? I put that there was no charge, but I also thought the choice saying that there was 0 V was also viable. I didn’t look into that question much.</p>
<p>For one of the car velocity questions (I forget the exact numbers), but you had to add the velocities to get the answer. It seemed like 50% of the questions in that section could have been answered knowing that negative (I think) meant that they were moving away from each other and that positive meant they were moving towards each other. </p>
<p>I’m gonna freak if I get these questions wrong.</p>
<p>^Yes you did have to add and the answer was -4.</p>
<p>Dont rmemeber the rate of CaCO3</p>
<p>At t=o q=o, the capacitor is uncharged.</p>
<p>Does anyone remember if most of the answers to the car section were A or F. I remember answering the first question of the car passage and then just skipping over to the next passage and filling in the leftover questions with A or F (the first answer choice).</p>
<p>i actually think i didn’t have any A’s or F’s on that, unfortunately. If I did, it was only one or two, max.</p>
<p>What do you guys think the curve for this Science is going to be?</p>
<p>Anyone remember their answer choices for the last science experiment? CaCo3? </p>
<p>C A C B A C? Something like that yes??</p>
<p>No. The last answers were D H B J C F. This has already been discussed.</p>
<p>jk :)</p>
<p>lol u scared me. I randomly put B for the third to last one but I’m not sure about it. And the last question was A, not C (pretty sure about this one). check post #166. that’s all i can tell you RAlec114.</p>
<p>I think this science was crap. I got a 33 and a 34 on the science on the previous ACT’s I took, and this one was a lot harder. For the two I took before, the science didn’t require any background knowledge, thank god. But with the periodic table question, the biology one, and the battery one, it was entirely dependent on taking those classes. Luckily for me, I’ve been taking IB Chem for the past 2 years, and we had just been making batteries in class the week before the ACT - so I was relatively fine there. But since I haven’t done biology since sophomore year, I got majorly owned by the gene thing. I think I BS’ed my way through most of it correctly, though.</p>
<p>I didn’t feel like this science section required too much prior knowledge. Maybe one or two questions, but that was it. The “periodic table” questions gave you the chart with all the information you needed, as did the battery questions. The biology one required a little bit of prior knowledge, but I haven’t taken biology since my freshman year (senior now), and I was fine on that one too.</p>
<p>Overall, it was a pretty difficult section, but the questions were reasonable. I finished under the time limit and felt well after answering every question.</p>
<p>yea same, i got a bunch of d’s from that one</p>
