Talk:Exothermic reaction

message: The merge debate goes back to '05 (see: Talk:Endergonic).  The result of the debate was to not merge.  Moreover, it is standard protocol, e.g. according to both The Essential Dictionary of Science (Clark 2004) and the A to Z Dictionary of Thermodynamics (Perrot 1998), to have separate entries for such closely-related but subtly-different topics such as:
:*Exothermic – a process or reaction that involves the release of energy; usually in the form of heat.
:*Exothermic reaction – a chemical reaction in which heat is give out.
As well as for the other terms: endothermic, endothermic reaction, etc.  For example, the melting of an ice-cube is an endothermic process; combustion evolves an exothermic reaction, warm-blooded animals are endothermic, arguing with other Wikipedians is an endergonic activity, etc.  Help us expand on these separate stubs, but please don't merge.  Wikipedia has unlimited storage space.  Articles are sure to grow.  Thanks:--Sadi Carnot 17:30, 22 March 2006 (UTC)

message: "The total energy in bond breaking is less than the total energy released in bond making."  The opening line of this article doesn't make any sense! Reddyuday (talk) 12:19, 31 December 2007 (UTC)
thread_title:  Doesn't make sense 

message: Couldn't locate any info on this page nor the decomposition page (the latter is rather heavily focused on forensics).  Would be happy if an expert could kindly put something in.  76.97.245.5 (talk) 05:52, 12 November 2008 (UTC)

message: I know this is pretty basic stuff, but it is still sketchy that there isn't a single reference on this page... — Preceding unsigned comment added by 207.188.75.13 (talk) 16:53, 24 February 2011 (UTC)

message: A literal translation would suggest this is only about heat, but what about light and sound?  —Preceding unsigned comment added by 110.175.121.168 (talk) 03:52, 5 March 2011 (UTC)

message: The change in enthalpy should not be −483.6 kJ/mol for 2H2 (g) + O2 (g) → 2H2O (g). It should be changed to -571.66 kJ/mol. — Preceding unsigned comment added by Bancho07 (talk • contribs) 14:49, 2 October 2023 (UTC)
replies: text: Not done: it's not clear what changes you want to be made. Please mention the specific changes in a "change X to Y" format and provide a reliable source if appropriate. M.Bitton (talk) 14:53, 2 October 2023 (UTC)
replies: text: The change in enthalpy depends only on the Standard enthaly of formation of water, because hydrogen and oxygen gases are elemental substances( their Standard enthaly of formation is 0). So using Hess's law to calculate the change in enthalpy we get -571.66 kJ/mol ,not −483.6 kJ/mol! — Preceding unsigned comment added by Bancho07 (talk • contribs) 17:43, 4 October 2023 (UTC)

text: Not done: please provide reliable sources that support the change you want to be made. We need sources for these things, calculations made by editors cannot be accepted as they are considered original research. —TechnoSquirrel69 (sigh) 00:19, 6 October 2023 (UTC)
