editIs the data for SO2 the same as for SO3? Adriansarli (talk) 16:29, 5 March 2010 (UTC)
Im not sure how to edit the data table myself. If someone who knows how could go ahead and and the following info on oxygen from Zumdahl Zumdahl Chemestry 6th edition that would be great.
O2(g) = 0
O(g) = 249
O3(g) = 143
hope someone gets on it. if not ill figure it out and overhaul the entire data table with all the data I have. --James Peterson —Preceding unsigned comment added by 207.172.87.196 (talk) 23:46, 27 February 2008 (UTC)
nothing shows up
The value for Carbon's ΔHfo (kJ/mol) should be POSITIVE, not negative! —Preceding unsigned comment added by 71.111.17.150 (talk) 05:27, 21 December 2007 (UTC)
=============
editmaybe its a stupid question but: is the ΔHf in kilocal of kilojoules??? I thinks it kilojoules. 1 kilocalorie = 4.18400 kilojoules. the values on this page seems to be kilojoules not kilocalories!!
Value for CO2 of -395.893:
Can't find this value anywhere else on the internet. Don't have my textbooks here
found textbooks, can only find values of close to -393.5 reverting change
"there are 2 different values given for some of the same substances: ethane first 20.0 than 83.85 Kj/mol" —Preceding unsigned comment added by 71.51.62.69 (talk) 08:14, 17 January 2010 (UTC)
kcal/mol vs. kJ/mol
editIs there some reason for the use of kcal/mol rather than the more standard kJ/mol for the upper table? (And for that matter, is there any reason for the second table?) --ES2 (talk) 05:40, 24 August 2012 (UTC)
