通过热化学循环,对非金属单质稳定存在形式、金属元素的最高氧化态、化合物的稳定性以及影响含氧酸热稳定性的物质结构因素等几个方面的问题进行了分析讨论,并提出有关见解。在无机化学中,过去着重从质变角度去讨论元素、化合物的性质及变化规律,而从能变来讨论则较薄弱。部分热力学内容的引入,能较全面地从质变和能变两个方面去探讨。本文通过恰当的热化学循环,说明某些元素化合物的性质以及确定影响某一过程进行的物质结构因素,将物质的宏观性质与其微观结构联系起来,较全面地探讨化学反应的发生及规律。
Through the thermochemical cycle, the existence of stable forms of non-metallic elements, the maximum oxidation state of the metal elements, the stability of the compounds and the material structure factors that affect the thermal stability of the oxo acids are discussed and discussed. opinion. In inorganic chemistry, the emphasis has been on the discussion of the nature and variation of the elements and compounds from a qualitative point of view, but the discussion from the point of view of energy becomes weaker. The introduction of some thermodynamic content can be more comprehensive from qualitative change and can change two aspects to explore. In this paper, through appropriate thermochemical cycles, the properties of certain elemental compounds and the physical structural factors that influence a certain process are discussed. The macroscopic properties of materials are related to their microstructures, and the occurrence and regularities of chemical reactions are more fully discussed.
