<p>did you notice the question about ph? they didn’t tell us bt i belive the lower the number the more acidic right?</p>
<p>@Noxsing
Yep, 6 is more acidic than 7 (which is neutral)</p>
<p>Yeah, I sub 0 was 8000, right? So that was letter answer J.</p>
<p>Was the ‘materials 1 and 2’ question the same one that asked which intensities couldn’t go above 10 or something? and was the answer of materials 1 and 2 choice A (or F)</p>
<p>@meat lol, we can only hope</p>
<p>For the question about which combination of acetone and water would make a 30% acetone solution, i said 100g water and 30 g acetone because then that would be a 100 ml solution with 3 parts acetone for every 10 parts water. Is this right…</p>
<p>Isn’t it 30g acetone and 70g water? So 100g total, and 30g out of that total is acetone?
Not sure though, I suck at science.</p>
<p>@llazar
I think I put that at first, then changed it to 30g aceton and 70g water. Then 30g/100g total would be 30%. Now I’m questioning myself again…</p>
<p>It was hard</p>
<p>what’d you guys put for the last two questions in the planets section? one was about the distance from stars and the other idk?</p>
<p>i’m pretty positive it was 30 and 70 because that makes 30/100 which is 30 percent</p>
<p>Was the ‘materials 1 and 2’ question the same one that asked which intensities couldn’t go above 10 or something? and was the answer of materials 1 and 2 choice A (or F)</p>
<p>What did you guys put for that one about the xhalf? I put 4.0.</p>
<p>^ I put 4.0 as well but I wasn’t too sure</p>
<p>@redkeyboard ^ okay that one really tripped me up because the question referred to experiment one but the numbers in the problem fit the data from experiment two…does anyone know what I’m talking about?</p>
<p>Its 30g and 70g because then you get the 30% acetone</p>
<p>Yankee I got the same answer, I thought the letter was b or g, not sure, but I think 1 and 2 are right</p>
<p>^I put 2, because 4 was x, and it asked for xhalf, which would’ve been 2. At least that’s my reasoning…</p>
<p>@yankeedood you’re right
@chillin apparently the it was far away, but I put closer. Another one towards the end of that section is that some planets would break orbit and eventually collide with their star.</p>
<p>@skylimits</p>
<p>Yea I wasn’t sure if something was wrong with my mind or what lol. Hopefully they meant Figure 2 cause it fit for that.</p>
<p>I didn’t understand the xhalf one…was it really 4? I guessed 1</p>
