<p>CO2 was the answer to two questions: its linear and it has 2 double bonds.</p>
<p>What was the question with some hydrocarbon particles breaking away from the surface of a solution of that hydrocarbon? Or was that just butane? :x</p>
<p>that was the True False question. i put T for it.. and T for the other pat but it was not the reason. when its sayin that it "breaks off" its talking about vapor pressure, which is higher than water meaning more of it breaks off than parts do for water. but the second part by no means explains it.</p>
<p>for the matching, u put octane as the answer for the liquid that is insoluble in water?</p>
<p>"u put octane as the answer for the liquid that is insoluble in water?"</p>
<p>Octane is organic; "like dissolves like", water is polar, organics are non-polar, therefore, octane does not dissolve in water</p>
<p>isnt octane a gas neway?</p>
<p>Let's see...</p>
<p>The nuclei of radioactive elements are unstable because there is a surplus of electrons in the nucleus.</p>
<p>CCl4 (or some tetrahedron, I forgot)..yadda yadda because it's not polar? LOL..I really don't remember..</p>
<p>All molecules (or was it atoms) of a particular element have the same mass because _______...</p>
<p>octane is a liquid. vadox i was right, right?</p>
<p>the radioactive one was T F. it was true that they have an unstable nucleus but electrons mean nothing in nuclear reactions.</p>
<p>CCl4 one was FT. it is NOT polar but it is a tetrahedron</p>
<p>the molecules one was FF. they are not all the same so F. i dont remember the second part.</p>
<p>CCL4 isn't polar because although electronegativity is different between C and CL, it's a tetrahedral so the differences cancel out.</p>
<p>All atoms of a particular element have the same mass because _______... was WRONG! All atoms of a particular element have the same number of PROTONS, neutrons can vary (which means mass varies)</p>
<p>Oh..and Ca has the electron configuration _________ because the d orbitals are lower in energy than the p orbitals. I got FF for that..</p>
<p>"Octane Solubility in water Immiscible"</p>
<p>From... Octane</a> - Wikipedia, the free encyclopedia</p>
<p>Oh..Hydrogen can be a reducing agent because ..........??</p>
<p>For Zn2+ -> Zn3+,, an oxidizing agent must be added?</p>
<p>HNO3 is a Bronsted acid because it accepts a proton...or w/e.</p>
<p>yes vadox i knwo its immiscible, so it was the ANSWER for that correct? lol.</p>
<p>hydrogen can be a reducing agent, but i dont remember the second part of the question</p>
<p>"For Zn2+ -> Zn3+,, an oxidizing agent must be added?"
it was Fe not Zn but yes, an oxidizing agent must be added</p>
<p>the acid one was True it is an acid but F because it doesnt not accept a proton, it donates it</p>
<p>when Sulfur becomes H2So4, it is reduced. FALSE. the next part however was true, it does go from 0 to +6, but that is oxidizing</p>
<p>6.02x10^23/2 for an answer??</p>
<p>H30+ and H20 aren't conjugate acid/base pairs... b/c H30+ = H+..aw crap. I confused myself on that one.</p>
<p>No, Fe was the element that exists as either 2+ or 3+.....</p>
<p>"H30+ and H20 aren't conjugate acid/base pairs..."</p>
<p>yes they are. the answer was H2O2 and H2O</p>
<p>maybe it was Zn, but still it was oxidizing agent haha</p>
<p>yea 6.02x10^23/2 was right</p>
<p>lets get some more discussion on this ppl! lol</p>
<p>Damn it..how did I miss one of the easiest questions?!? Grr</p>
<p>Wait, wasn't that question involving H2O and OH-? Or am I not remembering a question with H3O+ and H20?</p>
<p>it asked which ISNT a conjugate pair.</p>
<p>This thread is already dead? lolz.</p>
