Karel VlachovskýGood day,
I would like to write about potential mistake in Problem 3. Carnot cycle in Preparatory problems. There is written in hint pV^(1+R/Cv). However, if we had pV^(gamma)=const., gamma=Cp/Cv and Cp=Cv+nR then the hint would be pV^(1+nR/Cv). If I were wrong, I am sorry for bothering you.
2 fevral, 2015Karel VlachovskýThank you, I didn't notice 'molar' even after several readings...
2 fevral, 2015Science CommitteeIn this Problem, Cv is molar heat capacity, so n=1

Steven SmithWill the problems in the ICHO have the same concepts and topics as the preparatory problems? Or else how much would they be different from the preparatory problems?
3 fevral, 2015Science CommitteeAdvanced topics require reading university textbooks, for example: Atkins, "Physical Chemistry", Shriver, Atkins, "Inorganic chemistry",  Morrison, Boyd, “Organic Chemistry”, Skoog, "Fundamental of Analytical Chemistry”
2 fevral, 2015Steven SmithTo the Science Committee,Kindly tell me about some books or other sources or websites to study the topics of preparatory problems. Thanking you in anticipation.
1 fevral, 2015RuslanOf course, topics featured in preparatory are the ones to be featured on IChO.
1 fevral, 2015Science CommitteeOnly advanced topics will be the same as in preparatory problems

Ramón Sergio Trigueros DíazI write the following petition, to ask if you can authorize me to translate to Spanish the problems that lead to the 47th International Chemistry Olympiad, which will be held in Baku, Azerbaijan July 2015, so that the exercises can continue helping students who are currently participating in a workshop of this discipline.
23 yanvar, 2015Ramón Sergio Trigueros DíazThank you, my e-mail is quimicap7udg@gmail.com
20 yanvar, 2015IChO 2015The official language of IChO is English, so we will not post any translations of preparatory problems on the official web-site. However, you can leave your e-mail in the comments for those who are interested in Spanish version.
