| Sep 14, 2015 at 0:45 | comment | added | lirtosiast | Something to add on the combustibility point: Ammonia is also much less thermodynamically stable than water; its heat of formation is -46 kJ/mol vs -286 kJ/mol. So there are many other reactions that can destroy it. | |
| Nov 19, 2014 at 8:58 | comment | added | Irigi | @Twelfth I only wanted to say that 'ammonia is combustible' doesn't only mean hazard of fires. It means that after few (thousands) of years, there either will be no free ammonia or there will be no free oxygen. But maybe you meant the same, I just wanted to point it out. | |
| Nov 18, 2014 at 17:32 | comment | added | Twelfth | @irigi - exactly, it's what I meant by 'ammonia is combustible'. Free oxygen to any extent will react with ammonia and become water / NO2. There's a significant amount of hazardous material handling information around the combustibility of ammonia...apparently something thats only come up in more recent times too. | |
| Nov 18, 2014 at 10:44 | comment | added | Irigi | It seems to me that free oxygen in the atmosphere is quite unlikely on the ammonia world, it would quickly react with the ammonia. | |

| Oct 28, 2014 at 0:09 | comment | added | Twelfth | @TimB - After a little research...I'm really not sure if there is anything that could replace CA within shells that would not have the instant dissolve in Ammonia effect. If coral style life was to evolve in this, it'd have to pick a different set of elements to do so with. | |
| Oct 27, 2014 at 20:54 | comment | added | Twelfth | @celtschk - very true, river deltas would be especially metallic. My assertion was the Earth's 'conveyor belt' oceanic circulation is based on the density of water and in an ammonia world that would no longer be true...particulate would tend to drop to the very frozen bottom of the ocean and not be cycled around the world | |
| Oct 27, 2014 at 20:08 | comment | added | Tim B | @Twelfth Although there may well be an equivalent to shells that does evolve, and then rocks might form from that. I've no idea what that might be though. | |
| Oct 27, 2014 at 20:04 | comment | added | Twelfth | Very true @timB, I hadn't considered that it wouldn't form. Calcium based life (sea shells) wouldn't develop, nor would white beach sand as coral can be it's primary make-up. | |
| Oct 25, 2014 at 14:02 | comment | added | celtschk | Why do you think that rivers and lakes would have more dissolved materials than oceans? With water on earth, it's exactly the other way round: Oceans are salty because all the rivers put their minerals (salts) there, but evaporation doesn't remove them; rivers and lakes are generally less mineralized because the water in them is refreshed through (non-salty) rain, while the water flowing away takes the dissolved minerals with it. | |

Some quick grammar fixes

| Oct 25, 2014 at 6:30 | comment | added | Tim B | Limestone would be unlikely to exist in an Ammonia based world. Limestone is formed from calcium in the shells of sea life - sea life in an Ammonia liquid would not use calcium for exactly this reason so would have to use something else or have no shells at all. | |
