Yeah, YMSAT this week, so nothing much besides fixing up your respective exhibits and workshops, or study, sleep, or nothing, if that's what you want to do.
Edit from local Chinese man of Cesium:
Happy Birthday, Jade Emperor!!!
Chinese New Year Advice 1 for Ethan:
The greatest victory, is the battle not fought. (Also, please check Facebook)
Chinese New Year Advice 2 for Class:
Teachers open the door, but you must enter by yourself.
On a Personal Note:
新年快樂, Cesium. 今年是水龍年.水龍是很好的. 謝謝你給我一個值得紀念的過去一年, 我很要好的朋友.
(Rough Translation: Happy Chinese New Year, Cesium. This year is the year of the Water Dragon. The Water Dragon is very auspicious. Thank you for a very memorable past year, my good friends.)
Hey guys! We have a career fair on Thursday to Saturday and everyone is required to attend on the first 2 days. Here's the link to our schedule :)

Our era is the Regency Era, which is 1780's-1830's (debatable, but let's not fuss)
Math Hw: COle P. 760 2-10
For those without a book:
#02)
Prove using induction that:
1+4+7+...+(3n-2)=[n(3n-1)]/2
#10)
Prove using induction that:
13+23+33+...n3={[n(n+1)]/2}2

Use data in Appendix C to calculate for ΔHº, ΔSº, and ΔGº at 25ºC for each of the ff reactions. In each case show that ΔGº = ΔHº - TΔSº.
(a) Ni(s) + Cl2(g) → NiCl2(s)
(b) CaCO3(s, calcite) → CaO(s) + CO2(g)
( c) P4O10(s) + 6H2O(l) → 4H3PO4(aq)
(d) 2CH3OH(l) + 3O2(g) → 2CO2(g) + 4H2O(l)
(b) MgCl2(s) + H2O(l) → MgO(s) + 2HCl(g)
( c) 2NH3(g) → N2H4(g) + H2(g)
(d) 2NOCl(g) → 2NO(g) + Cl2(g)
19.32
Predict the sign of ΔSsys for each of the following processes:
19.34
Using Appendix C to compare the standard enthalpies at 25ºC for the following pairs of substances. For each pair, explain the difference in entropy values.
19.38
Calculate ΔSo values for the following reactions by using tabulated So values from Appendix C. In each case, explain the sign of So.
(a)N2H4(g) + H2(g) → 2NH3(g)
(b) Al(s) + 3Cl2 → 2AlCl3
(c) Mg(OH)2 + 2HCl (g) → MgCl2(s) +2H2O(l)
(d) 2CH4 → C2H6(g) + H2(g)
19.16
A (picture shows 4 molecules in each flask with 5, 7, 8, and 4 in the left and 1 2 3 and 6 in the other)
b. is your answer in part A consistent with our expectation that the gas molecules, on average, distribute themselves equally between two flasks? Explain.
B. What is the sign of (Delta)S for the process?
C. What is the significance of the statement that entropy is a state function?
