<p>also, what were the other questions in that set?</p>
<p>yeah for co2 i said true and then false.</p>
<p>what were the questions?</p>
<p>k and na are not isotops</p>
<p>what exactly was the diamond and quartz question? i remember putting TTCE</p>
<p>i said you could have an electron in a radioactive reaction</p>
<p>same with me. ; diamond and graphite is f/t. The q was diamond and graphite have the same structure because the are noth pure forms of carbon.</p>
<p>Wait I meant for the co2 that I put T T</p>
<p>oh right! i put f/t too!</p>
<p>Oh well I got one wrong for sure. Was Cs the most reactive in water? Is Na the elemental one or w/e. the last tf was t/t/ce. the diamond and quartz did not have same structure but were composed of carbons i put so f/t</p>
<p>cs is the most reactive in water because it is an alkali metal. I don't understand your second question:( I don't rememeberr the last t/f</p>
<p>what was the question on isomers, isotopes, allotropes and all that?</p>
<p>oh it was o2 and o3 what are they? i said allotropes.</p>
<p>co2 forms an acid?</p>
<p>for potassium and water I put just H2...is that wrong?</p>
<p>yes, they're allotropes</p>
<p>i put isotopes, i had no clue what an allortrope was. one qu.estion asked for which one isn't in the elemental state and i put NA. And yes co2 forms an acid but not a STRONG acid.</p>
<p>i hate how you can't rip the periodic table out of the book. =[</p>
<p>i said cs was the most reactive in water.</p>
<p>okay maybe i didn't do as bad as i thought. but if i omit 8 does anyone have an idea of what score i got if i got everything else right?</p>
<p>do you guys think i should cancel?</p>
<p>omitting 8 if you get all the rest right should be pretty close to 800...I'd say 770+</p>
<p>it's allotropes; agree with Gyros on the acid</p>
<p>I put allotropes and that CO2 formed an acid as well. I don't remember the exact question but what was the answer to the question about collection of gas over water or something; the choices might have been Roman numeral with O2, H2, HCl.</p>
<p>^about maybe 770 +</p>
<p>I put O2 and H2 only</p>
<p>Yeah it is allotropes. What's the curve for this test. The Barron's says a raw score of 70 out of 85 is 780-800.</p>
<p>i put Na as the elemental one too.</p>
<p>and for sure you can have an election as a product of a radioactive reaction. was that the question though? i'm starting to doubt myself.</p>
<p>Well i know there is an radioactive partile "electron"</p>
<p>Proton is 1
1</p>
<p>Neutron is O
1</p>
<p>Electron is 1
0</p>
<p>I think this is right. Oh and electrons DONT take up 1/3 mass. They have negligibile weight.</p>
