Why objects at night are not the same colour as when they were in the day? I think the problem is that the reaction: is spontaneous, meaning that it proceeds (slowly) in standard conditions with no other inputs required. Annals of Philosophy 2: 443454. In fact, you can write any compound in any order-- for example, you could call ethylenediamine--which in the book is NH2CH2CH2NH2-- N2C2H8, or C2N2H8, or even H8N2C2, but the reason why it's written the way it is in the book, is to emphasize the order of bonding when drawing Lewis structures, or to clarify concepts. 1995.
