<p>hey where can i find explanations to the chem subject test questions in the collegeboard subject test book?</p>

<p>thanks</p>

<p>it should be in the back. or after a practice test. Like it shoudl have the test, then the answers, then explanations. some books don't have explanations. make sure yours does. this may sound really stupid, but I took the test two years ago and I didnt do that bad but I coulve done better had I know you're not allowed to use a calculator. As I said thsi may soudn stupid becasue it sounded like everyone but me knew, but just in case you didnt know i hope it helps! Good luck!</p>

<h1>101 Statement 2 - Dunno</h1>

<h1>105 Statement 2 - Equilibrium can only be changed by Temperature and Pressure.</h1>

<h1>12 - the Cu2+ accounts for 2 Cu, so the I- = 4</h1>

<h1>13 - I don't know sorry.</h1>

<h1>15 - PF3 is trigonal pyramidal because it has 4 electron pairs but 1 of which is a Lone pair, which is not bonded to anything.</h1>

<h1>19 - Well, since it's 0.5 mol you divided what you get by half. So 4 moles of O is actually 4 x 0.5 x 6.02 x 10^23 (Avagadros Number; Mole) = 1.2 x 10^24.</h1>

<h1>20 - Well, there's 2 atoms in O2 and 3 atoms in CO2, so CO2 wil always be more dense than O2.</h1>
