<p>@collegetime18 Try checking previous frq’s and see what the grading rubric is… That might give you an idea</p>

<p>@NewJersey25‌ HF does not dissociate that much since it’s not a strong acid. HF-> and <- into H+ and F-. The F- then reacts with H20 to make HF and OH-. This is how it relates to acids and bases. </p>

<p>hey how would you find the bond order for so3 and a sulfite ion?</p>

<p>@hawkace Thanks! :)>- </p>

<p>Is anyone studying MO theory</p>

<ol>
<li>Do we need to know flame test colors and precipitate colors?</li>
<li>I still dont know what labs we are suppose to study, since there is more emphasis on experiments</li>
</ol>

<p>I don’t think we need to know flame colors and precipitate colors… I think we should just know he concepts behind experiments and what will happen if you were to change a few variables.</p>

<p>MO theory is not on the test </p>

<p>but what experiments , I know there are like 16 and I only know PES, titration, and calorimeter</p>

<p>I was wondering if someone could explain this answer to me. My review book gives me a question on Ksp and it gives me ksp values for Lithium carbonate, Nickel (II) carbonate and strontium carbonate. The ksp values are 8.15E-4, 1.42E-7 and 5.60E-10 respectively. The question asks “in order to precipitate the maximum amount of carbonate ions from the solution, which of the following should be added to the carbonate solution: LiNO3, Ni(NO3)2 or Sr(NO3)2?” The answer is Sr(NO3)2 and I am not sure as to why. I would think that the compound with the highest ksp would precipitate the most carbonate ions. Thanks for your help in advance!</p>

<p>Actually is Sr(NO3)2 because its the most insoluble so you’ll get the most precipitate? I think the wording tripped me up. </p>

<p>Do you guys think that the score range for a 5 will be smaller and that the range for a 4 will simply be extended higher? I couldn’t care less whether I get a 4 or a 5, and if getting a little bit above 50% is all it takes to get a 4 then I think I can relax a little bit. If I’m completely wrong somebody please correct me. I’m really trying my best to stay calm.</p>

<p>@hazelheart I think that something over 50% is def a 4 or a 5. </p>

<p>How important is the photoelectron spectra on the exam?</p>

<p>Should you use 4.18 or 4.19 for the specific heat of water? </p>

<p>Also, does anyone have a list of formulas that should be memorized? </p>

<p>BEER’S LAW. ANYONE?</p>

<p>how come no one is answering my question? What experiments do we have to know for the exam?</p>

<p>when do we use polarizability to explain ideas?</p>
