<p>Does anyone remember what they got for the question in the multiple choice section where there was 20 mL of O2 and 40 mL of SO2 and it asked like the volume of the product produced?</p>
<p>It was 40 ml. The relationship was a 1 : 1 between SO2 and the product (don’t remember), so stochiometrically, since we are dealing with gases and a complete reaction, 40ml of SO2 yields 40ml of the product gas.</p>
<p>if anyone has taken the sat ii chemistry exam before june 2013, could you please give me a surmise about how difficult it was compared to this one</p>
<p>@TheGreatCatsbyx it was MUCH harder than the May test ! I got a 730 on that one and i’m hoping for better this time</p>
<p>Can someone explain to me the test tube and water pressure TTCE question? I got FT.</p>
<p>For the T/F/CE hydrocarbon question… why wouldn’t it be F/F since hydrocarbons can also contain other elements besides hydrogen and carbon, such as the halogens?</p>
<p>Did anyone else get T,F for the gas diagram one? I thought the gas inside the tube is equal to the atmospheric pressure the vapor pressure not just the atmospheric pressure</p>
<p>and the last one was all the partial pressures had to at up to 760 right?</p>
<p>[ATSDR</a> - Chemical Class - Hydrocarbons (contain hydrogen and carbon atoms)](<a href=“Toxic Substances Portal | ATSDR”>Toxic Substances Portal | ATSDR)
“Hydrocarbons are a class of chemicals that contain only hydrogen and carbon atoms.”</p>
<p>Ok this is probably a dumb question but for some reason I blanked out on the test when it came to gases, so I didn’t understand the question in the TFTFCE section that had something to do with volume and speed of gases at a constant temperature or something like that. What did y’all put for it?</p>
<p>I got FT. False because the water level couldn’t have changed unless we changed atmospheric pressure as there wasn’t any source of new gas. True because when the water levels are equal the total pressure inside the tube is equal to atmospheric pressure.</p>
<p>@gmann That’s what I put for the partial pressures one. And I got T T CE for the gas diagram one but I pretty much just guessed.</p>
<p>How much would 6 wrong be?</p>

Here’s an approximate curve according to SparkNotes: [SparkNotes:</a> SAT Chemistry: Scoring the SAT II Chemistry](<a href=“SparkNotes: Today's Most Popular Study Guides”>SparkNotes: Today's Most Popular Study Guides)</p>
<p>6 wrong will translate to a raw score of 77, which is about a 780. This is an approximation, so who knows if this is accurate. Anyways, I wouldn’t stress over predicting your score. What’s done is done.</p>

<p>Does anyone remember the questions with the PHASE DIAGRAM of water?
I totally blanked out on that one</p>
<p>It was A E C.
The line between the solid and liquid phase. Line between solid and gas phase. And in the gas phase.</p>
<p>For the ttce question on the inverted test tube in a beaker of water, I got FT. Not really positive on that though.</p>
<p>I got the same as Harrovian for the diagram i think.</p>
<p>so for the hydrocarbon question it was F T?</p>
<p>@jguskadoo yes it was F, T.</p>
