硝酸盐受热易分解,分解产物非常复杂,不要求学生掌握其分解的规律,但试题中往往以信息的形式给出,它常常将氧化还原反应原理、氮的氧化物与氧气溶于水的计算融为一体来考查.旨在考查学生灵活处理信息的能力,由于它涉及内容多、思维含量高、而备受命题者的青 Nitrate is easily decomposed by heat, and the decomposition products are very complicated. Students are not required to master the law of decomposition, but the questions are often given in the form of information. It often interprets the principle of redox reaction, the dissolution of nitrogen oxides and oxygen in water. Integrate to examine. It is designed to examine students’ ability to handle information flexibly, because it involves many content, high content of thinking, and the propositional person
