Chemistry June 2014 Regents Discussion

<p>@connetquotreppin‌ I agree. And I got some of them. </p>

<p>For the significant figure question, did you guys get 3? I HATE SIG FIGS</p>

<p>@tpny1026‌ I got 3</p>

<p>@tpny1026 I got 3 also, and 0.111M?</p>

<p>@bloodythunder Yeah i got .111 too if I remember correctly</p>

<p>Do you guys remember what you put for that multiple choice question about a reaction and which reaction would change the substance or something?
I think i put burning whatever the compound was</p>

<p>The balanced equation was already balanced. You cant balance ions lol. What did everyone say for the question where one gram of a compound was dissolved in an 100 g cup or something. I choose one, the only insoluble anwser.
What did you guys say for:
the question with N02 and N20. Was is: different structures and properties?</p>

<p>Burning propane </p>

<p>@tpny1026‌ same</p>

<p>@crazysteve‌ it said it was unbalanced and you had to balance the electrons. </p>

<p>@crazysteve I put different structures and properties</p>

<p>@tpny1026‌ I put burning propane, I assumed they meant combustion</p>

<p>Also, what did you guys say for the first model with electrons? I put Thompson but wasn’t sure between that and Bohr.</p>

<p>@bloodythunder‌ yep
Guys for the titration one, I put .11, will that be an issue, or am I good?</p>

<p>@Indiangurl It depends it they want it to the correct number of significant figures or not (3). I’d assume they won’t take double off if you got that one wrong, so it might depend for how many significant figures you stated the answer should be.</p>

<p>Does anyone remember what they got for the molarity short answer? I got .3 but I think I’m wrong.
And also there was one multiple choice about which released the most heat, I think I got choice 3 the one that has -81 ?</p>

<p>@bloodythunder well I said three significant figures, but the question itself never specified the number of figures I had to use.</p>

<p>@littlet4lks‌ nah it was 4, some bigger #</p>

<p>@Saswizy‌ i could of been a trick question</p>

<p>Not true for the potassium bonding it is an ionic bonding. </p>

<p>What wa the answer for the amount remaining after the half life or something? I got 1/2 since it was one half life…</p>
