Re: Chemical reaction question « Reply #3 on: April 12, 2018, 09:05:43 AM » Thanks for replyingI read that hydrogen gas reacts with acid to result in calcium sulphate. Acid is something that has spare electrons (if I trust wiki’s definition). Would the CaCO3 (limestone) and ...
The results will be needed to develop an approach for the Integrated Management System (IMS) for such post-industrial abandon areas. Chemical formula of compounds used in this article. Aluminium sulphate (Al2(SO4)3), arsenate (AsO43−), arsenopyrite (FeAsS), arsine (AsH3), barium chloride ...

为了识别化学式中存在的表示原子个数的下标空间关系,我们引入了"_"来代表下标关系,在给样本打标签的时候把""加入含有数字下标的前面,即CaCO3被标注为CaCO_3,Ca2(OH)2CO3被标注为Ca_2(OH)_2CO_3.通过大量样本的监督学习,系统会自动学习其中的空间关系,在遇到同类的空间关系时,自动识别输出代表下标信息的""...
