<p>one about measuring volume of reagent in a titration
something about separating solids w/ different solubilities or something?
and another with a stop ****
I put:</p>
<p>1) Burette
2) Fractional distillation or filter, whichever was there
(Fractional Distillation is separating miscible liq and liq. Filter paper and funnel are for solid/liq separation)
3) Burette has a stop **** (stopcock can close and open it)</p>
<p>isomer problem</p>
<p>a) has only one carbon. so can not be an isomer.
b,c,d,e have several carbons with double bond, Cl etc. They can be isomers</p>

Which of the following can the Kinetic Molecular Theory not describe?</p>
<p>(A) Something dependence on something (temperature or pressure or volume)
(B) Something dependence on something (temperature or pressure or volume)
(C) Something dependence on something (temperature or pressure or volume)
(D) Diffusion of gases
(E) Heats of formation</p>
<p>Which of the following can the Kinetic Molecular Theory not describe?</p>
<p>(A) P dependence on T
(B) V dependence on T
(C) P dependence on V
(D) Rate of Diffusion of gases
(E) Heats of reaction
ans is E, too obvious.</p>
<p>Yay 800</p>
<p>For al amohoterism</p>
<p>3h+ + al3- -> h3al
3oh- + al3+ -> al(oh)3</p>

i put the one with 22.4x 300/273 x 150/760
think it was D?
anyone know how to do that one? </p>
<p>it should be
22.4x 300/273 x 760/150</p>

What was the one about what exhibits most ionic behavior?
CsF, LiF, NaCl, etc I put CsF…
Also, the one with Na2SO4 - x H2O, 9g H2O? I got 10</p>
<p>CsF
Na2SO4 10H2O correct
(9 g H2O is 0.5 mol, Na2SO4 is 0.05mol, so 1:10 ratio)</p>
