<p>so the final answer is....</p>
<p>Lets make a consolidated list. For the first questions, was there two answer choices with lead? Like which one is a metal and which one always has a positive oxidation state? Also, the green-yellow gas is chlorine right? And the yellow solid is sulfur?</p>
<p>just because two things happen together doesn't mean one causes the other. it is true that being linear helps being nonpolar, the benzene molecule is nonpolar but its not linear. the fact that the diatomic molecules are linear doesn't make it polar, you have plenty of polar diatomic molecules like HF.</p>
<p>The final answer for that question was T T.</p>
<p>how do you join the CHEMISTRYST chatroom? help plz</p>
<p>def T T for linear non-polar diatomic. it totes would have been CE if B said something about same electronegativity.. bee tee dubs what was the KE causal question?</p>
<p>I think that is also TT</p>
<p>^bump</p>
<p>plz</p>
<p>nice. do you think this test is easier or harder than most? im hoping the curve is somewhat lenient</p>
<p>i though its easier.</p>
<p>i still think the diatomic linear one is F T. A diatomic molecule doesnt have to be nonpolar. Diatomic isnt only N2 or F2, but anything with 2 atoms. Thus it could be polar</p>
<p>I'm pretty sure they're only referring to diatomic molecules. I've never heard of the term diatomic being used on elements other than H2, O2, F2 etc</p>
<p>was the BF3 a tetrahedral? or was it trigonal pyramidal</p>
<p>BF3 is triagonal planar since Boron can only hold 6 valence electrons</p>
<p>Perhaps ppod you are right Maybe CB is playing a trick on us.</p>
<p>ppod1991- thats a valid point, actually. ill go with darksideofmoon (i liked wish you were here most). trigonal planar.</p>
<p>and it was a beta emission? (nuclear question)</p>
<p>anyone remember the coefficients for balancing questions?
i think i put the answer '1' for the BaSO4 or whathever that was (relatively long) balancing question.
are you guys sure about the total energy being KE + PE? btws, I put TT, but NOT TTCE for that, because yes increasing temperature does increase speed and total energy (i think) equals KE + PE, but it's not directly a 'because relationship...
Does anyone have a definite answer to the filter paper question? Was it only III (precipitate)?
Also, the weak electrolytes question. It was CCl4 yea?
Decomposition question was the one where H2O2 separated into two other compounds?</p>
<p>How do we know that there was 0.5 moles Hydrogen gas?
Usually when H2 and O2 are combined, water forms, making the reactant side of the equation 2H2 + O2 right?
So wouldn't it be 1 mole of H2 since there was 0.5 mole O2?</p>
<p>linear = symmertical = nonpolar?</p>
<p>^ Volume was at 22.1 (STP), so there has to be 1 mole total</p>
