<p>@AwesomeFreezer But H doesn’t have an atomic # of 2… Only He does</p>
<p>@deeperplease I just put lithium cause its the best at losing. (Oxidation Is Losing)</p>
<p>@AwesomeFreezer no it was he because only h has a atomic number of 1. And 1±1 is 0. But he has an atomic number of 2. </p>
<p>How do you even balance a redox with coefficient? </p>
<p>@deeperplease I just balanced it as I normally would. I got all ones tho… That one got to me…</p>
<p>@Indiangurl on the top it says the equation is an unbalanced ionic equation. cant be all 1s</p>
<p>Oh. I’m not really sure then</p>
<p>What do you need to get 75</p>
<p>For the redox I got 3 2 3 2</p>
<p>For the redox balancing ewuation, i got 1-2-3-1. And for a 75 I think you need like 15-25 raw points off</p>
<p>What did you get for graphite and diamond MC question? I put different isotopes but I think it was crystalline structure</p>
<p>@connetquotreppin It was crystalline structure </p>
<p>@Saswizy for the redox balancing question, it was (zn0) + (al+3) -> (fe+2) + (something0)… How did you get those coefficients?</p>
<p>@connetquotreppin You have to seperate the oxidation and reduction half reactions:</p>
<p>Zn0–> Zn+3 + 3e-s
Fe+2 + 2e-s --> Fe0</p>
<p>(Or whatever the elements were) since the reactions need to balance mass, energy, and charge. The masses are equal, the energy is equal, but the charge is not. To do this we multiple the equation by a number to balance out electrons lost and gained</p>
<p>2(Zn0–> Zn+3 + 3e-s)
3(Fe+2 + 2e-s --> Fe0)</p>
<p>2Zn0 --> 2Zn+3 + 6e-s
3Fe+2 + 6e-s --> 3Fe0</p>
<p>Remove the electrons from the equation and we have:</p>
<p>2Zn0 + 3Fe+2 --> 2Zn+3 + 3Fe0</p>
<p>^^or that, it was all 3s and 2s</p>
<p>If I get a 85 + on all 3 science regents, do I get a separate diploma for mastery?</p>
<p>The curve for chemistry is so terrible…</p>
<p>It’s actually really bad…</p>
<p>Yeah it favors people who are borderline passing. Very unfair considering it is a tough and rigorous course. Did you guys get your other regents scores?</p>
<p>Yep, if you get one MC question wrong, that’s a 96 (I think). Agh I think I may have gotten one wrong, possibly two because of careless errors. /:</p>
<p>@connetquotreppin - Yeah!</p>
